I am using Python 2.7 through Anaconda 2.7.8 and need Kapteyn 2.2 to perform Non-linear Least Squares fitting easily (it is probably an alternative to Scipy.optimize.leastsq() for dummies like me!).
After copy-pasting this from a previous post here on Stack Overflow:
conda install -c https://conda.binstar.org/dhirschfeld pyodbc
and then running on my cmd (as I did not have pyodbc installed I think, because of which maybe the command prompt on my Windows 7 64-bit system was not responding well to python setup.py install inside the Anaconda directory where I unzipped the Kapteyn .zip file downloaded from University of Groningen website.
But, after the installing pyodbc properly and running python setup.py install, the cmd gave me an error saying error: command 'C:\Users\windows 7\Anaconda\Scripts\gcc.bat' failed with exit status 1. Later, when I tried to import kmpfit module (needed for Non-linear least square fitting with Kapteyn), here is the problem:
import kapteyn
help(kapteyn)

As you can see, there is no module named kmpfit (or even wcs) here. But according to http://www.astro.rug.nl/software/kapteyn/intro.html, these two should be there.
Kindly help. I have never imported any module before.
Thanks in advance...:-)
I just managed to get this working (on Mac OSX, so you may have to adjust this). My steps were:
$ conda install pyodbc (didn't need to go through binstar)
Download & unarchive the kapteyn package, then navigate to its directory
$ python setup.py install, which used my OS's C compiler and Anaconda's python, and installed kapteyn to my anaconda distro's site-packages, as it should.
Check that kmpfit.so is in the kapteyn folder in site-packages, showing that kmpfit installed correctly.
>> from kapteyn import kmpfit failed, ImportError: cannot import name kmpfit. I did some digging and discovered that it was still importing kapteyn from the folder that I downloaded, not from site-packages.
Delete the downloaded kapteyn folder, then try again. It worked!

I want to install PyMesh on a Windows 10 PC, if possible it should be installed in the side-packages of an interpreter delivered with the IDE we use.
I tried the way to run the setup discribed here
https://pymesh.readthedocs.io/en/latest/installation.html
so the part :
git clone https://github.com/PyMesh/PyMesh.git
cd PyMesh
git submodule update --init
worked without any problems.
I am not sure on windows if I now just can write
set PYMESH_PATH = path
and if i can use the path "...\PyMesh\PyMesh" here?
so i left out this part
I installed numpy and scipy (allready installed)
and nose because it is mentioned in the requirements.txt.
So my numpy scipy and nose versions are
numpy 1.19.1
scipy 1.6.0
nose 1.3.7 (same as requirenments)
and just run the setup.py with admin rights
python .\setup.py install
which also seemed to work but i got an error trying
python -c "import pymesh; pymesh.test()"
from the PyMesh folder
saying ModuleNotFoundError: No module named 'PyMesh'
or if i go up one Folder doing the same
saying AttributeError: module 'PyMesh' has no attribute 'triangle'
I found this link ImportError: No module named PyMesh
but i just dont know what i should type in there
I tried to install via pip by using pip install pymesh
but pip Installer gives me a different library.
So i tried in the docker version and in docker i tried the pymesh.load_mesh method with an stl File
but got
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape
I dont know if this is just the stl format (expecting binary getting ascii or vice versa)
The stl file itself can be opened so shouldnt be corrupted.
So is there a different way to install pymesh? A wheel would be great. Is it possible to install pymesh to the side-packages of a given Interpreter? Did someone else allready had the same error in Docker and knows the issue
thank you for your help
I've been trying to install matplotlib and textblob on my system using
pip3 install matplotlib
or
pip3 install textblob
It says it's installed successfully. However, when I try to import in in Sublime Text it says
ModuleNotFoundError: No module named 'matplotlib'
or
ModuleNotFoundError: No module named 'textblob'
I've set up the build system in sublime text for python 3. A lot of modules that I've installed and are using the same way works fine (BeautifulSoup, requests and tweepy for example). I do not understand why some modules work and others do not. I've been trying to find the solution to this problem but after hours of research without results, I see this question as my last resort. Very thankful for all help.
shell_cmd: /usr/bin/env python3
Working on Automate The Boring Stuff project and having trouble with pyperclip and IDLE. pyperclip is successfully downloaded and works fine in Terminal but when I import pyperclip in IDLE, I get the below error.
UPDATE - This is happening with other modules - anything I've installed in the terminal aren't importing into IDLE.
import pyperclip
Traceback (most recent call last):
File "", line 1, in
import pyperclip
ModuleNotFoundError: No module named 'pyperclip'
I figure I have the module saved in the wrong folder somehow. Below are the sys.path outputs from my Terminal and IDLE.
In terminal:
'/anaconda/bin',
'//anaconda/lib/python36.zip',
'//anaconda/lib/python3.6',
'//anaconda/lib/python3.6/lib-dynload',
'//anaconda/lib/python3.6/site-packages',
'//anaconda/lib/python3.6/site-packages/Sphinx-1.5.1-py3.6.egg',
'//anaconda/lib/python3.6/site-packages/aeosa',
'//anaconda/lib/python3.6/site-packages/IPython/extensions',
'/Users/andrewricardo/.ipython']
In IDLE:
sys.path
['', '/Users/andrewricardo/Documents', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python36.zip', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages']
There are multiple paths here - how do I effectively move the pyperclip module to the correct place?
OR - Is there something else going on here?
Each python installation and uses its own .../lib/site-packages for 3rd party modules, and you have two. If you ran the non-anaconda python in the terminal, the same that is running IDLE, it would have the same problem. Indeed, that python is the source of the ImportErrors.
Option 1: Separately install all packages you want to use with the non-anaconda python (and IDLE) in its own site-package directory. In IDLE Shell, get the path to its executable
>>> import sys; sys.executable
Save are remember the resulting 'python-path'. Then in the terminal, run
python-path -m pip install package-name
for each package.
Option 2 (uses a little known feature of site-package directories): in
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages
add a file name, for instance, anaconda.pth, containing one line.
//anaconda/lib/python3.6/site-packages
(I have no idea why the double / or if it is really needed; I just copied it from your question.) This makes the anaconda python site-packages an extension of the framework python site-packages. Since both are for 3.6, one copy should work for both.
Had this same issue and googled
'why is importing pyperclip in my python file giving an "modulenotfounderror"but working fine in the idle'
and this page came up. then i also checked this [installed Pyperclip, trouble importing to IDLE.
I am new to python, had the same issue using the same book after pip installing pyperclip here's what I did to solve this issue.
I copied the pyperclip-1.7.0-py3.7.egg-info and pyperclip folders from
C:\Users\USER\AppData\Local\Programs\Python\Python37\Lib\site-packages into the C:\Users\USER\Anaconda3\Lib\site-packages folders and C:\Users\USER\AppData\Local\Programs\Python\Python37 folders and it worked. Hope this helps. If it doesn't. Try this code in your text editor because that's what I did using Atom and how i was able to solve it.
import sys
print(sys.executable)
Then copy the pyperclip-1.7.0-py3.7.egg-info and pyperclip folders into the path that the above code gives you.
I am running Python 3.5 on Windows 8. I am trying to install pygame. I downloaded and ran
pygame-1.9.2a0.win32-py3.2.msi (6.4 Mb)
from
http://www.pygame.org/download.shtml
From python I get, after starting a new session:
>>> import pygame
Traceback (most recent call last):
File "<pyshell#6>", line 1, in <module>
import pygame
ImportError: No module named 'pygame'
How do I install? Was my PythonPath updated? Looking at sys.path, it doesn't look like it. How do I get Python to see the library? Where was the library installed? Thanks for the help.
Update1:
The first step i the pygame intsaller states "Select Python Installations - Select the locations where pygame-1.9.2a0 should be installed." Underneath that is a selection that states "Python from another location". This doesn't make sense to me. Anyone?
Update2: I solved the problem - I reinstalled python in the default location (it wasn't before). The pygame installer doesn't seem to support custom installations. Ok, fixed. Thanks all for the help.
Up to now, Windows binaries must match the Python binaries. ...py-3.2.msi is for 3.2 and will not work with 3.5. Either get a 3.5 binary from the site you already used or use pip to install pygame-1.9.2a0-cp35-none-win32.whl from http://www.lfd.uci.edu/~gohlke/pythonlibs/ Use pip install /? to get info on how to install from somewhere other than pypi. It might be easier to download the file to your machine first. The site above says a bit about this.
Make sure you have 32-bit python and pygame.
I have python2.7.8 on mac, things I did:
sudo easy_install pip - worked.
pip install numpy:
Requirement already satisfied (use --upgrade to upgrade): numpy in /System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
I also did "pip upgrade numpy" - no luck. What's wrong?
Your problem is a conflict of different Python versions.
I would recommend installing Python and all the packages, such as numpy, scipy, matplotlib, pandas, etc via Brew
See this tutorial: https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/Homebrew-and-Python.md
You can verify which Python you're running with which python or which python3 in Terminal.
This solution is more flexible and cleaner in my opinion than using Conda/Miniconda. However it is also a bit more lengthy to install, as you need to have Xcode, devtools installed to build everything
Could it be that you have multiple versions of python installed? What happens if you run python using the full path like this:
$ /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python2
instead of just python2?
In my experience on Mac (and other OS too) it is best to go with Anaconda / Miniconda. This is especially true for packages like NumPy and others from scientific stack.
While Anaconda is a full-blown distribution with about 200 packages, Miniconda is just Python with a few basic libraries. The big advantage is that all packages install as binary. Further, it makes it very simple and stable to install multiple Python versions side by side. For example:
conda create -n py27 python=2.7
creates a new environment with Python 2.7. Activate with:
source activate py27
Now:
conda install numpy
installs NumPy cleanly.
You can do the same for Python 3.5 and switch between environments with source activate.
After jumping from one stackoverflow answer to another I found the solution!
my problems were:
numpy at different location( actually at right, expected-to-be location). It was the IDLE that looks for its own default folder where python2.7 installed.
I checked that my numpy is working like this, run this script to check it is working:
import os
import sys
import pygame
sys.path.insert(0, '/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python')
import numpy
pygame.init()
print "( using __version__): " + numpy.__version__
print numpy.version.version
user_paths = os.environ['PYTHONPATH']
print(user_paths)
sys.path insertion adds additional path to IDLE, so it knows where to look for numpy.
Then I check if numpy truly imported - i just print its version. Right now it is 1.8.0rc.
I want to find a way to avoid using this syspath insertion all the time.
So far so good - for now.
I had a similiar problem with numpy. However, it was resolved by choosing the right environment. If you are using VScode, open the command palette (ctrl+shift+p) and type
Python: Select Interpreter.
From there, try choosing the right virtual environment/Interpreter.
