How to set working directory pemanently in Spyder & RStudio? - rstudio

I have started learning - Machine learning course on Windows OS. Whenever I start a new instance of Spyder 3.2.4(Python 3.6) & RStudio(1.1.383), every time I need to set my current working directory in these IDEs. Is there any way to set them pemanently?

In Spyder (since version 3.2) you need to go to
Tools > Preferences > Current working directory
and select the option called
the following directory

To set working directory permanently in:
1. Spyder IDE: Tools > Prefeences > Current working directory > the following directory
2. RStudio IDE: Tools > Global Options... > General > Default working directory (when not in a project)
PS: Yes, we need to restart the application in both IDEs to take
changes in effect.

In Spyder whenever you run your script for the first time it will go to current directory automatically. You just have to run for the first time.
Make sure you have selected
Tools > Preferences > Current working directory

For Mac:
Click "python" in top left corner.
Click preferences.
Current working directory.
Boom.

Install adt Package [duplicate]

In PyCharm, I've added the Python environment /usr/bin/python. However,
from gnuradio import gr
fails as an undefined reference. However, it works fine in the Python interpreter from the command line.
GNURadio works fine with python outside of Pycharm. Everything is installed and configured how I want it.
Gnuradio is located at /usr/local/lib/python2.7/site-packages/gnuradio
Also:
PYTHONPATH=/usr/local/lib/python2.7/site-packages:/usr/local/lib/python2.7/site-packages/gnuradio
Adding a Path
Go into File → Settings → Project Settings → Project Interpreter.
Then press configure interpreter, and navigate to the "Paths" tab.
Press the + button in the Paths area. You can put the path to the module you'd like it to recognize.
But I don't know the path..
Open the python interpreter where you can import the module.
>> import gnuradio
>> gnuradio.__file__
"path/to/gnuradio"
Most commonly you'll have a folder structure like this:
foobarbaz/
gnuradio/
__init__.py
other_file.py
You want to add foobarbaz to the path here.
You should never need to modify the path directly, either through environment variables or sys.path. Whether you use the os (ex. apt-get), or pip in a virtualenv, packages will be installed to a location already on the path.
In your example, GNU Radio is installed to the system Python 2's standard site-packages location, which is already in the path. Pointing PyCharm at the correct interpreter is enough; if it isn't there is something else wrong that isn't apparent. It may be that /usr/bin/python does not point to the same interpreter that GNU Radio was installed in; try pointing specifically at the python2.7 binary. Or, PyCharm used to be somewhat bad at detecting packages; File > Invalidate Caches > Invalidate and Restart would tell it to rescan.
This answer will cover how you should set up a project environment, install packages in different scenarios, and configure PyCharm. I refer multiple times to the Python Packaging User Guide, written by the same group that maintains the official Python packaging tools.
The correct way to develop a Python application is with a virtualenv. Packages and version are installed without affecting the system or other projects. PyCharm has a built-in interface to create a virtualenv and install packages. Or you can create it from the command line and then point PyCharm at it.
$ cd MyProject
$ python2 -m virtualenv env
$ . env/bin/activate
$ pip install -U pip setuptools # get the latest versions
$ pip install flask # install other packages
In your PyCharm project, go to File > Settings > Project > Project Interpreter. If you used virtualenvwrapper or PyCharm to create the env, then it should show up in the menu. If not, click the gear, choose Add Local, and locate the Python binary in the env. PyCharm will display all the packages in the selected env.
In some cases, such as with GNU Radio, there is no package to install with pip, the package was installed system-wide when you install the rest of GNU Radio (ex. apt-get install gnuradio). In this case, you should still use a virtualenv, but you'll need to make it aware of this system package.
$ python2 -m virtualenv --system-site-packages env
Unfortunately it looks a little messy, because all system packages will now appear in your env, but they are just links, you can still safely install or upgrade packages without affecting the system.
In some cases, you will have multiple local packages you're developing, and will want one project to use the other package. In this case you might think you have to add the local package to the other project's path, but this is not the case. You should install your package in development mode. All this requires is adding a setup.py file to your package, which will be required anyway to properly distribute and deploy the package later.
Minimal setup.py for your first project:
from setuptools import setup, find_packages
setup(
name='mypackage',
version='0.1',
packages=find_packages(),
)
Then install it in your second project's env:
$ pip install -e /path/to/first/project
For me, it was just a matter of marking the directory as a source root.
Add path in PyCharm 2017
File -> Settings (or Ctrl+Alt+S) -> Project -> Project Interpreter
Show all
Select bottom icon on the right side
Click on the plus button to add new path to your module
My version is PyCharm Professional edition 3.4, and the Adding a Path part is different.
You can go to "Preferences" --> "Project Interpreter". Choose the tool button at the right top corner.
Then choose "More..." --> "Show path for the selected interpreter" --> "Add". Then you can add a path.
DON'T change the interpreter path.
Change the project structure instead:
File -> Settings -> Project -> Project structure -> Add content root
In PyCharm 2020.1 CE and Professional, you can add a path to your project's Python interpreter by doing the following:
1) Click the interpreter in the bottom right corner of the project and select 'Interpreter Settings'
2) Click the settings button to the right of the interpreter name and select 'Show All':
3) Make sure your project's interpreter is selected and click the fifth button in the bottom toolbar, 'show paths for the selected interpreter':
4) Click the '+' button in the bottom toolbar and add a path to the folder containing your module:
For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.
As quick n dirty fix, this worked for me:
Adding this 2 lines before the problematic import:
import sys
sys.path.append('C:\\Python27\\Lib\site-packages')
On Project Explorer, you can right click on the folder where the module is contained and set as 'Source'.
It will be parsed in the Index for code completion as well as other items.
I'm new to PyCharm (using 2018.3.4 CE) and Python so I rotely tried to follow each of the above suggestions to access the PIL (Pillow) package which I knew was in system-site-packages. None worked. I was about to give up for the night when I happened to notice the venv/pyvenv.cfg file under my project in the Project Explorer window. I found the line "include-system-site-packages = false" in that file and so I changed it to "true". Problem solved.
In my PyCharm 2019.3, select the project, then File ---> Settings, then Project: YourProjectName, in 'Project Interpreter', click the interpreter or settings, ---> Show all... ---> Select the current interpreter ---> Show paths for the selected interpreter ---> then click 'Add' to add your library, in my case, it is a wheel package
For me there is also another issue. If you try to add a folder that in the past had a .idea folder, but your current project has it's own .idea folder your pycharm might get confused for some reason -- even if you have the right python/conda env. For me deleting the .idea folder of the other project fixed the confusion that it could find the obviously correctly installed pkgs. Then it was it was able to find them in the pycharm editor GUI snf stopped underlyinging them in red.

Cannot find git while installing foundation

I am new to ZURB Foundation and trying to install it through Ruby CLI.
I have successfully installed ZURB Foundation and now I want to create a new project with this command:
foundation new myFound
It gives me an error saying:
Can't find Git.
I have installed Git on my system but still have this error. I run on Windows. Any suggestions?
You have to check this option during the installation to add Git on PATH:
Use Git from the Windows Command Promt
Picture
If you didn't do it you can reinstall the Git or add it on the PATH manually (I assume that your Git's installation folder is C:\Program Files (x86)\Git - if doesn't, change it to yours).
Command line approach
set PATH=%PATH%;C:\Program Files (x86)\Git\bin
Graphical approach
Select Computer from the Start menu
Choose System Properties from the context menu
Click Advanced system settings > Advanced tab
Click on Environment Variables
Select Path in the section System Variables and edit it
add ;C:\Program Files (x86)\Git\bin at the end and save it

Recreating PyCharm launcher in Ubuntu

I installed pycharm normally via bin/pycharm.sh, but the mistake I made was doing bash pycharm.sh while the pycharm directory has inside the Downloads folder.
I later on moved the directory to /opt/Pycharm/. This is causing the once functioning unity launcher (which was added when PyCharm was initially installed) to fail every time I attempt to use it (as expected).
How can I re-add pycharm.sh as a lauchable app from the unity launcher? I know the location of the pycharm.sh file. I've tried to add it to /usr/bin/ but that does not change anything.
I can still launch pycharm via bash /usr/opt/Pycharm/bin/Pycharm.sh. But this is tedious.
UPDATE
I have tried making a new .desktop file for pycharm, using the following script:
[Desktop Entry]
Encoding=UTF-8
Name=PyCharm
Exec=/opt/Pycharm-3.0.1/bin/pycharm.sh
Icon=/opt/Pycharm-3.0.1/bin/PyCharm_32.png
Type=Application
Categories=Development;
StartupWMClass=PyCharm
However, I get a "Unable to save Pycharm.desktop" error when I try to save the file inside /usr/share/applications/pycharm.desktop. Any help regarding this would be deeply appreciated.
First start pyCharm from it's bin folder via command line
$ ./pycharm.sh
Then, goto
Tools -> Create Desktop Entry.
It will create a correct Desktop file in the correct place. Afterward you can initiate it from the menu and pin the icon or drag and drop it to the bar. This way, you don't have to deal with .desktop files and mumbo jumbo..
I managed to solve it. The thing is, Pycharm already installs a launcher inside .local/share/applications. Thus, you need to get rid of it before proceeding to create your own. After that, all you have to do is add your own *.desktop file to the applications directory inside usr/share/applications/.
You need to create your .desktop file using sudo and inside the desktop file:
[Desktop Entry]
Encoding=UTF-8
Name=PyCharm
Exec=/opt/pycharm-3.0.1/bin/pycharm.sh
Icon=/opt/pycharm-3.0.1/bin/pyCharm.png # Changed from pycharm_32.png
Type=Application
Categories=Development;
StartupWMClass=PyCharm
After that is done, you can launch your app properly. Please note that pycharm.sh must also have execution rights.
With Ubuntu 16.04, I used the "snap" installer, which doesn't include an easily accessible icon (there's probably one hidden inside the snap image, but it's hard to get at). Instead it shows a grey question mark icon in the launcher instead. Also there doesn't seem to be a Tools > Create Desktop Entry option in version 2017.3.3 as far as I can see - maybe it has been moved somewhere.
So I copied pycharm.png from an earlier non-snap Community installation, saved it somewhere, then created ~/.local/share/applications/jetbrains-pycharm-ce.desktop:
[Desktop Entry]
Version=1.0
Type=Application
Name=PyCharm Community Edition
Icon=/path/to/pycharm.png
Exec="/snap/bin/pycharm-community" %f
Comment=The Drive to Develop
Categories=Development;IDE;
Terminal=false
StartupWMClass=jetbrains-pycharm-ce
Then when I start PyCharm (from the command line), the launcher item appears with the correct icon, and then I right-click on it and choose "Lock to Launcher", and it now persists.
A downside is that the icon will not be automatically updated with the app, so it might fall out of date.
In case you just want to update your launcher to point to an updated PyCharm, for me changing 4.0.4 to 4.0.6 in the following worked:
nano /usr/share/applications/jetbrains-pycharm.desktop
When Tools -> Create Desktop Entry does not work:
Create a new file on your desktop (using vi or a similar command) named: jetbrains-pycharm.desktop
Paste the following inside:
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Type=Application
Name=PyCharm
Icon=/opt/pycharm-5.0.1/bin/pycharm.png
Exec="/opt/pycharm-5.0.1/bin/pycharm.sh" %f
Comment=Develop with pleasure!
Categories=Development;IDE;
Terminal=false
StartupWMClass=jetbrains-pycharm
Keep in mind to change the path and version number of icon and exec properties above.
Tested on various versions of PyCharm - like a charm ☺
In the 2016 version of PyCharm just do following:
Start PyCharm.
From the Tools menu, select "Create Desktop Entry..."
Create entry for "all the users" if required.
Relaunch PyCharm from Launcher.
Ubuntu 16.04 (haven't checked prior versions)
Run pycharm.sh (make sure you use the correct dir and PyCharm version below):
$ ./dir_where_you_placed_it/pycharm-2016.1.4/bin/pycharm.sh
While PyCharm is running, right click its icon on the Launcher and select "lock to Launcher".
Run $ pycharm-community
Right after you will see the icon on the taskbar.
Right Click, select Lock on the Taskbar.
Somewhat solves the problem.
Simply replaced the Icon=/path/to/pycharm.pngin ~/.local/share/applications/jetbrains-pycharm-ce.desktop from meowsqueak's answer with the correct path when installed from snap.
[Desktop Entry]
Version=1.0
Type=Application
Name=PyCharm Community Edition
Icon=/snap/pycharm-community/current/bin/pycharm.png
Exec="/snap/bin/pycharm-community" %f
Comment=The Drive to Develop
Categories=Development;IDE;
Terminal=false
StartupWMClass=jetbrains-pycharm-ce
sudo vim `which charm`
Now edit the RUN_PATH.
I recently resolved a related issue where, after updating from v2.7 to v3.0.2, my PyCharm launcher was still pointing to the old (and now deleted) PyCharm path.
After attempting all of the (good) advice above, the problem still persisted.
The solution, in my case, was to create a desktop entry for ALL USERS.
[Welcome Screen]->Configure->Create Desktop Entry...
Check the box: "Create entry for all users" and then proceed.
Apparently, in a previous installation I must have installed it in this fashion and was not able to update the launcher for a single account.
Now the pycharm updated to version 2016.1 and I find the file jetbrains-pycharm.desktop in the path ~/.local/share/applications
then just edit the path for Icon and Exec
Simply type this on your terminal window:
jetbrains-pycharm.desktop
Hope that helps :)
I just wanted to add, I just installed PyCharm Edu for Ubuntu 16.04 LTS today, and the way to create a desktop entry is very easy. When PyCharm Edu opens up, before entering any project, click on configure, and there should be a create Desktop Entry option. Select it, and it will create a PyCharm Edu.desktop file in the following directory:
/usr/local/share/applications
Now traverse to that destination, and click the newly created PyCharm Edu.desktop file to launch PyCharm Edu. After that, you would just need to lock to launcher. It should work.
I know I am very late, but I hope I've helped those of us on Ubuntu 16.04 LTS who are trying to configure a desktop entry for this specific application.
I guess you didn't check 'Create the entry for all users (requires superuser privileges)' option on Tools -> Create Desktop Entry. You should check it.
You don't have to create something new.
you can always use python for automation
may be this will help you
a python script that allows u to run pycharm as user or sudoers/root
import os
from time import sleep
sleep(1)
program = input('which program to run: >')
if program == "pycharm":
os.chdir('#full path to pycharm paste here')
root = input('run as root(y/n): >')
if root == 'y':
print('started ' + program + ' as root')
sleep(0.5)
print('please enter root password to continue:')
os.system('sudo ./pycharm.sh')
elif root == 'n':
print('running ' + program + ' as non root')
os.system('./pycharm.sh')
elif program != 'pycharm':
print('program not found')
I have an LXDE desktop (on Debian Buster) and using PyCharm CE 2020.2.3. Choosing Create Desktop Entry... created nothing on the desktop, no matter whether Create the entry for all users was checked or not.
However, the PyCharm menu entry (under Programming) offers a context menu entry Add to desktop. Clicking this finally made the desktop icon appear.

sass not recognised using Windows command shell

I've installed ruby and the sass gem on a Win 7 Enterprise box. I've had issues throughout the process, and had to download the gems and install them from local to avoid other issues.
gem install --local sass-3.1.19.gem
I'm trying sass --watch styles.sass:styles.css but I get the standard sass isn't recognised error from the command line.
I'm really new to ruby so I could well have missed a step.
Thanks in advance
In order to run commands without specifying full path, you need to have the path to the program in you PATH variable.
So if your program is located in C:\Programs\rubygems\gem\sass you'll need to add C:\Programs\rubygems\gem\ to PATH.
The process of adding a folder to PATH for the Windows command line prompt is described here.
For Windows Powershell, please check Setting Windows PowerShell path variable here on SO.
After installing sass with NPM you got this:
npm install -g sass
file:///C:/Users/yourName/AppData/Roaming/npm/sass ->
C:/Users/Administrador/AppData/Roaming/npm/node_modules/sass/sass.js
You can create the path. Go to environment variables - > system variables -> path -> Edith , and include file:///C:/Users/yourName/AppData/Roaming/npm/sass. Then, Accept everything. and it's done.
Yes, putting the path to my ruby bin did indeed solve this.
My Computer --> right click, Properties --> Advanced system settings (left hand column) --> Environment variables --> find Path in the bottom list, highlight and edit --> include ;c:\path-to-ruby\bin at the end --> OK back out through the windows.
Thanks!
If you using Windows 10 v1607 (latest update as March 2017), you need to follow following steps:
Right-click on start menu & select System
Click on Advanced System Settings (left hand column)
Click on Environment variables button
In top section, select Path (or PATH), then click on Edit button
Inside opened window, click on New button
In selected input area, type (for ex.) C:\Ruby22-x64\bin\ (its must be path to ruby's bin folder)
Click OK, twice
Re-open Command-Prompt, now sass is ready to watch and compile your sass files.
If you have Node installed use the node terminal instead of the windows/VSCode terminal.
Search for the Node terminal on the windows search tool placed on the right side of the windows start button.

Change the working directory in Xcode

I managed to get my C++ project running in Xcode using cmake -G Xcode. Now I would like to debug it, because of the nice gdb fronted it provides.
However I need to change the working directory where gdb is executed otherwise it wont work. (It needs to read some data from files relative to the path of the working directory) What I can do is after gdb has stopped typing cd working_dir and then run it manually typing r. This works, but Xcode will complain constantly and is also not an elegant solution.
So somewhere in the build settings I should be able to set the working directory..but where?!
Just updating this solution to XCode 4.x
You go on Product -> Scheme -> Edit Scheme
On the tab Options you choose your working directory.
In Xcode 4 the working directory settings is under Scheme Settings.
In Xcode 3.x do a "Get Info" on the executable and look at the first tab - there is a setting there for working directory.
The default debug working directory is somewhere under ~/Library/Developer/Xcode/DerivedData/project-/Build/Products/Debug. You're better off using the full path.
