I have been trying to run Javascript from a Jupyter Notebook on Windows 10 but failed miserably. It seems I cannot install IJavascript to make it available.
All installation guides say to use Anaconda for IJavascript - so I did, but I CANNOT FIND IJAVASCRIPT anywhere within Anaconda, only the js packages, i searched everywhere there was a search bar available. So, because I am stubborn i tried the hard way:
Installed all javascript packages except mocha (which cannot be found) listed here:
https://anaconda.org/javascript/repo
then tried
npm install -g ijavascript
but keep getting this error:
c:\users\ryuuzako\anaconda3\scripts\node_modules\ijavascript\node_modules\nan\nan_json.h(89): error C2660: 'v8::JSON::P
arse': function does not take 2 arguments [C:\Users\ryuuzako\Anaconda3\Scripts\node_modules\ijavascript\node_modules\ze
romq\build\zmq.vcxproj]
"Javascript" type does not appear when creating a new file in Jupyter, my guess is because ijavascript is not installed..
ANY suggestion to make it work is greatly appreciated.
I can provide the whole npm log but it is humongous.
Feel free to assume i am a complete idiot who didn't work with node before.
I've just forked ijavascript and edited the documentation for the Windows installation section as shown below.
Windows
Install Python3 or the Anaconda3 Python distribution.
In the command line:
pip3 install --upgrade pip
pip3 install jupyter
npm install -g ijavascript
ijsinstall
If the ijinstall command is not recognized, you can execute it manually by navigating to your npm install directory and running the ijinstall batch file. If you do not know where your npm install is located, try looking for it in the default install location: C:\Users\USERNAME\AppData\Roaming\npm.
Then you can run jupyter notebook in your terminal to load Jupyter Notebook. When you create a new Jupyter Notebook, you should see the Javascript (Node) kernel available.
If using the Anaconda alternative to the standard Python distribution, it comes pre-installed with Jupyter Notebook. If using Anaconda, you can skip the pip3 install jupyter step.
This picture might also help, when it comes to the ijinstall part.
I struggled with this as well. After installing by running commands:
pip install jupyter
npm install -g ijavascript
You will need to update the environment variable named 'Path' in the 'System Variables' section.
In Windows 10, Python 3.10, the path to add looks like:
C:\Users\your-windows-user\AppData\Roaming\Python\Python310\Scripts
After changing the environment variable, you will need to re-start the computer for it to take effect.
Once this is done, run:
ijsinstall
in the command prompt and you should be good to go.
This also happeed to me.
First thing install anaconda after that(by default you have installed jupyter),
then search in your menu apps for anaconda prompt, then install ijavascript from anaconda prompt:
npm install -g ijavascript
ijsinstall
then run jupyter from anaconda prompt
jupyter notebook

Unable to run the rasa init command and getting following error:
'rasa' is not recognized as an internal or external command, operable program or batch file.
I have following version of RASA in my environment:
rasa-core 0.13.2
rasa-core-sdk 0.12.2
rasa-nlu 0.14.6
rasa-sdk 1.2.0
Sams answer is right. Rasa is probably not in your environment variable path.
Have you already tried:
py -m rasa init
or
python -m rasa init
If this doesn't work you may find answers at the rasa community forum
Did you try pip based installation as mentioned here
You can do
pip install rasa
If you have already done that I suspect that you need to add rasa in the environment variable PATH
Also are you using virtualenv? or conda environment? I would suggest using that to do the installation.
I had this issue with python 3.9. It worked after downgrading the python version to 3.8. It required recreating my conda environment.
Hopefully you got it working by now, but if not you can either
1) Try setting the Python path in Advanced System Settings > Environment Variables. (ideally we want it in a top-level folder)
2) Re-install Python using the graphical installer. Run the regular Python installer as administrator. BE SURE to click the little ‘Add to PATH’ checkbox, or all this will be for naught!! (For me personally this is a lot easier than manually adjusting the path in environment variables.)
Then choose “Custom install location.” Clicking “Install for all users” should automatically change the install path to the C:Program Files folder.
3) You may also be able to do this without a full reinstall by selecting Programs > Programs and Features > Modify/Repair.
Go to Settings -> Manage App Execution Aliases -> Turn Python Off - since I had both Python and Python3 enabled, the VSCODE was not letting me access the virtual environment I created in the Project Folder. This solved my issue.
Wrong Path in cmd Terminal of VSCODE:
C:\User....\Project>rasa --version
'rasa' was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
Correct Path in cmd Terminal of VSCODE (after turning off Python in Computer App Settings):
(venv) C:\User....\Project>rasa --version
Rasa Version : 2.3.4
Rasa SDK Version : 2.3.1
Rasa X Version : 0.37.1
Python Version : 3.7.10
The accepted answer says to set the environment variables which made me curious but the problem is I do not know the rasa installation path to set the environment variables.
Step 1:
So I'll write down how I figured this out. First, if you don't have the Anaconda package manager install it from the official website. (While installing click the checkbox to add Anaconda to your PATH environment variable.)
Step 2:
Now open up the anaconda prompt and go to the directory where you want to run rasa.
Step 3:
Then we can create a new conda environment by running conda create --name installingrasa python==3.8.5 to keep all of our dependencies together in a centralized place. Finally activate the environment by conda activate installingrasa
Step 4:
Install UJSON and Tensorflow that will help us to work with rasa.
conda install ujson
conda install tensorflow
Step 5:
Ultimately we can install rasa. Here we are going to install it via pip rather than conda. (there is no conda version fr rasa at the moment I'm writing this)
pip install rasa
Step 6:
In order to run Tensorflow on windows, we need to download visual c++ separately. Find the executable from the official website. And now we can run rasa init without errors and initialize new bot.
try this code while creating a virtual environment
conda create --name filename python==3.8
Looks like this is an issue of python 3.9. After playing around a lot with 3.9, I downgraded my python to 3.8 and it worked without a glitch.
You can create a conda environment with a different python version by using the option python==3.8 in the conda create command line.
The above solutions didn't worked for me.
After a lot of searching I found that rasa was located at C:\Users\tejas\AppData\Roaming\Python\Python36\Scripts\rasa.py (installed using pip install rasa)
As I was working anaconda environment named as(RASA)
I didn’t found rasa.py at C:\Users\tejas\anaconda3\envs\RASA\Scripts nor in
C:\Users\tejas\anaconda3\Scripts
So I just copy pasted rasa.py at these 2 locations and it worked for me in anaconda environment.
You might forget to install the rasa package. You can follow the steps to install rasa on your machine.
Create a new virtual environment named venv
You can also install rasa without virtual environment. but it would be better to track the dependencies if we are in a virtual environment.
python3 -m venv venv
Activate the virtual environment
For windows: venv\Scripts\activate
For Ubuntu: source ./venv/bin/activate
Install rasa package
pip3 install -U pip
pip3 install rasa
For more: Rasa installation
Try this command,
pip3 install -U --user pip && pip3 install rasa
It worked for me, This command will upgrade your pip to the latest version, and rasa will be successfully installed, and check it by typing rasa --version.
If it still doesn't work, download the python 3.7 version using miniconda,set the environment using miniconda, and then install rasa using this command again
The Jupyter notebook worked initially, but I tried importing tensorflow and that would not work, so that led to me messing up everything.
I basically messed everything up, and I feel like the only way out now is to just nuke my device and restart. I had no idea what pip and anaconda are (still don't really), tried a bunch of funky updates and installations and whatever and now everything is just dead. My jupyter notebook cannot even run the normal python kernel.
How can I hard reset everything?
As a bonus, if someone were to ELI5 the difference between conda, pip, gitbash, and PowerShell are. And what versions of stuff does Jupyter run on (since my conda and device had different versions of things I think?). I use Windows 10.
My first piece of advice is to not use Windows, though I'll probably get downvote spam for that. On Ubuntu, I could stuff Jupyter setup into one line:
# update, install python3, python3-dev, and pip3; get pip packages
sudo apt-get update && sudo apt-get install -y python3 python3-dev python3-pip && sudo -H python3 -m pip install jupyter notebook ipykernel tensorflow
Once the packages are installed, it's as easy as running jupyter notebook in the terminal.
Anaconda is a distribution of Python that includes a ton of pre-built packages, including Jupyter and scipy, numpy, pandas, etc. It's an "out of the box" solution basically, that comes with most of the tools you need. "Pip" is a package manager for Python; pip install [package] lets you use a package in your script, like import [package]. In this case, that's tensorflow.
ipykernel is a package that will open up a Python kernel for Jupyter. You could run a Jupyter notebook on a Python3.7 backend but do stuff with Python2 code by installing ipykernel with Python2's pip, usually (on Ubuntu) sudo apt-get update && sudo apt-get install -y python-pip && sudo -H python -m pip install ipykernel.
What happens when you run jupter notebook? Do you get errors? Can you get the notebook to open, but there's just no kernel to attach to a notebook?
I have just set up a new Windows 10 machine for Python, Jupyter, and Tensorflow. I did the set-up without anaconda. I did the normal set-up procedure with some special steps:
1) Python 3.8 und Jupyter as installed by "pip install" does not work. You need to add three lines of code in a module that is installed as dependency when you install Jupyter. change asyncio.py
2) Current Tensorflow does not work with Python 3.8. You need to install Python 3.7. You don't need to delete your Python 3.8 if you have one. Create a virtual environment with virtualenv as described here and give the Path to your Python 3.7 Special Python in virtualenv
3) If you want to use GPU for NVIDIA in Tensorflow, you need to deal with the fact that two things do not fit together: current Tensorflow and the current version of ‘NVIDIA GPU Computing Toolkit’ (a tools you need for GPU support). Take a look here for the fix: cudart64_XYZ.dll not found
Let's start with the basics:
As a bonus, if someone were to ELI5 the difference between conda, pip, gitbash, and powershell are
You probably know the classical cmd.exe which opens a basic terminal where you can use different commands and call programs from. It is basically a text based way to interact with your operating system.
Powershell is in my understanding just an extension of this (I don't use it myself) and has more capabilities of what you can do and also better scripting support.
gitbash is an optional tool that you probably installed when you installed git on your computer. It emulates a bash shell that many people are used to from different operating system like ubuntu where bash is often the default terminal and therefore makes it easier to use, as all the syntax and commands are then the same as these ppl are used.
Neither of these is in any way directly related to using python on your computer other than being able to type python or jupyter notebook into these terminals to start the applications.
To the more python specific questions:
conda is a package and virtual environment management tool. It can be used to install a variety of software and also create virtual environments to keep different set ups seperate from one another (e.g. different python versions on the same machine). But it is not limited to python. It is pre-installed when you download and install miniconda or anaconda which are two python distributions.
pip is a package manager only for python packages and comes pre-installed with most python distributions.
anaconda/miniconda , often times confused with conda are two python distributions, i.e. what you would consider as "I installed python on my system" that come with the conda package manager pre-installed. miniconda does thereby not ship any other packages while anaconda comes with a long list of useful packages pre-installed and is therefore a popular choice when you want an easy acces into using python for your research
For more info, you can also read understanding-conda-and-pip
How can you save your system now
I basically fucked everything up
Difficult to access the current state of your system, but I would suggest you try the following steps to get to a working condition again:
Go into Setting -> Apps and remove everything that is related to python or anaconda. Make sure that everything is deleted by also searching (using windows search feature) for python or conda folders somewhere in C:\Users. This should make sure that everything about your setup is purged
Make sure that neither python, pip or jupyter commands are working anymore in your cmd (confirming the purge)
Download and install miniconda
Now Create a virtual environment and install tf. This is a good way to go because if you should manage to f*k up the environment, you can just delete and recreate it without much trouble:
conda create -n venv pip python=3.7 #create environment
conda activate venv #activate the environment
conda install jupyter #for jupyter notebook
pip install https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-2.1.0-cp37-cp37m-win_amd64.whl
Start jupyter notebook: jupyter notebook. Since it only exists in this environment, same as tensorflow, there should be no more issues to use tensorflow normally
I'm brand new to Python. I've been using Python through Anaconda. I'm running Python 3.6.5. Right now, I'm trying to install a package called USZIPCODE from https://pypi.org/project/zipcodes/. I downloaded the zip file from this site in to my downloads folder. I then tried to use $ pip install uszipcode from the CMD prompt. This doesn't work. "Invalid Syntax" is returned. I've looked at videos on how to use pip to install other packages but they have not been able to solve my problem. The picture below should give some insight in to the issue. Any pointers on how I can install this package into python? Thank you! enter image description here
2 years too late to help bbranham, but for other Anaconda Python beginners having trouble using pip install, use the "Anaconda Powershell Prompt". For instance, on Windows 7:
Hit the windows key and type "Anaconda Powershell Prompt" and select in the search bar to open the Anaconda Powershell cmd prompt.
If you are using different environments make sure to activate your environment with conda activate yourenvname
pip install uszipcode should work out then (to download and install the uszipcode package to your active anaconda environment).
Tried installing pixiedust for debugging functionality in Jupyter. Using standard conda environment , python 3.5 and following https://ibm-watson-data-lab.github.io/pixiedust/install.html
Up to "pip install pixiedust", everything is fine, but
"jupyter pixiedust install" reveals several modules which are not installed.. I suspect this may be wrong, and that they should have been installed by the pixiedust? After adding 5-6 modules (conda / pip) I gave up.. What is wrong? Having a good debugger would be nice for jupyter.
I had the same problem here. I use python 3 and ubuntu, but when I type 'pip install pixiedust', it was installing in python 2 (ubuntu's default).
What worked for me:
pip3 install pixiedust
pip3 install pixiedust_node
With that I can use the %%pixie_debugger in my cells and it works just fine.
My question is thoroughly based on this question. The big difference is I'm focusing on windows here. The answers/question provided there were for unix distributions.
I've ran Python 2.x for quite a while and have used pip with no problems.
Now I've installed python 3 but when I open the cmd prompt and pip install somemodule it tries to install it for python 2. How can I deal with this situation ?
Both Python's were installed with the Anaconda distribution so I believe both of them come with pip installed. Note: This info come from this question
EDIT:
Found this answer which addresses that issue.
But now when I try to run the command
pip3.5 install pymssql
or
pip-3.5 install pymssql
I get the error pip3.5 is an unknown command.
If I open cmd and type python I receive:
Python 3.5.1 Anaconda 4.0.0
so it shouldn't be a version problem
You will want to make sure you have the correct Anaconda environment activated, which it looks like you have in this case.
conda env list # Display the list of conda environments
In the Windows Command Prompt you should just need to use:
activate py35 # Or whatever your Python 3.5 environment is called. (Mine is root)
pip install pymssql
Instead of pip-3.5.
To install it in another environment (mine is called py27):
activate py27
pip install pymssql
I successfully used this command in both my Python 2.7 and 3.5 Anaconda environments.
To go back to your primary environment (root), just type activate without an environment name after it
