I have python versions 3.6.5_1 and 3.7.0installed via Homebrew.
jupyter needs python3.6 for launching. It wouldn't start if I switch to python3.7.
After launching, it fails to start the kernel. Giving this error:

From what I understand, the kernel is looking for python3.7. My kernel list has just python3
$jupyter kernelspec list
Available kernels:
python3 /usr/local/etc/jupyter/kernels/python3
I looked at this link on github, but it wasn't helpful. How do I make jupyter and the kernel running on the same python version?
Check the kernel specifications:
$jupyter kernelspec list
This will show you the available kernels. In this case:
python3 /usr/local/etc/jupyter/kernels/python3
Open the kernel.json file in this directory and specify the path of python you want the kernel to use in the argv key.
Updating the jupyter notebook resolved the issue for me.
But remember, update it using command line. Not Anaconda Navigator
pip install -U jupyter
In case anyone anyone reading this who runs Jupyter Notebook from within Anaconda and gets the same error:
I found a workaround by installing Jupyter using pip in the command prompt (not anaconda prompt):
$pip install jupyter
and then start Jupyter using the known way
$cd 'DirectoryofyourNotebook'
$jupyter notebook
step 2 command:
conda activate <location of your env folder>
step 3 command:
python -m ipykernel install --user
works!
I had same issue - tried all the above without success.
Context: using Windows on that machine, for a few years. I have used this machine as a "code on the go when I need to" laptop and have not been very careful nor consistent when installing/upgrading python versions or libraries or environments.
The fix for me - somehow a folder that contained f2py.exe (Numpy - on top of which Pandas is built) was not in the path and was in a hidden folder that ended with "\Scripts". Python itself was fine in the environment variables. They were in very different folders - while normally they should be in close branches in the folder tree. Adding the full path of the folder ending with "\Scripts" that have f2py.exe in the environment variables solved the kernel issue for me.

Conda environments not showing up in Jupyter Notebook
(24 answers)
Closed 1 year ago.
I have put several days into sorting out the problem of conda's python virtual environments not recognizing the kernels they were build around. The problem manifests as both Spyder and Jupyter-notebook failing to start with a valid kernel. Here is an example of a conda environment built for kernel 3.8.10 specifically to run pymc3 (per pymc3 environment requirements) and how it fails in the jupyter-notebook also selected and installed specifically in that environment.
The only thing I know for sure: the error message is totally misleading. The win3api dll seems to have nothing to do with the actual problem
Does anyone recognize this? Are there tweaks that will get me going? Or is this another case of Rip-out-and-reinstall-Anaconda3? Which is a familiar refrain.

```
First, make sure your environment is activated with conda activate myenv
Next, install ipykernel which provides the IPython kernel for Jupyter:
pip install --user ipykernel
Next you can add your virtual environment to Jupyter by typing:
python -m ipykernel install --user --name=myenv
This should print the following:
Installed kernelspec myenv in /home/user/.local/share/jupyter/kernels/myenv
In this folder you will find a kernel.json file which should look the following way if you did everything correctly:
{
"argv": [
"/home/user/anaconda3/envs/myenv/bin/python",
"-m",
"ipykernel_launcher",
"-f",
"{connection_file}"
],
"display_name": "myenv",
"language": "python"
}
That's it!
I had python 3.8 and jupyter notebook running in visual studio code before. After I installed Anaconda, I cannot run jupyter notebook any longer and am getting a Kernel error.

I have tried conda install ipykernel --update-deps and conda install pywin32 but the issue persists. How can I fix this?
This suggestion worked for me: pip uninstall pywin32 and then conda install it again:
https://github.com/jupyter/notebook/issues/4980#issuecomment-663885620
how to use pip from conda:
Open Anaconda.
Select Environments in the left hand pane below home.
Just to the right of where you selected and below the "search environments" bar, you should see base(root). Click on it.
A triangle pointing right should appear, click on it an select "open terminal"
Use the regular pip install command here.
then how to install pywin32 using anaconda:
ran conda install from anaconda prompt as admin per this website, https://anaconda.org/anaconda/pywin32 :
conda install -c anaconda pywin32
I am totally new to this. So I installed pipenv using 'pip install pipenv'. I have python version 3.8.2, pip version 20.1.1 and pipenv version 2020.6.2 .
But when I try to run 'pipenv install' it gives the following error.

Thank you for your time.
I think the newer version of pipenv is causing the error, I use this command when having the same issue and it worked for me, just use
pip install pipenv==2018.10.13
I had the same problem when I uninstalled Anaconda. Mine got solved after I did the following steps
run regedit.exe
Go to
Computer\HKEY_CURRENT_USER\Software\Python\PythonCore
If there is/are folders having previous versions of python.Delete every version of python other than your current one(for eg.3.7, 3.8 etc. I also had to delete some folder containing something related to anaconda to solve the problem (other than the previous versions)
I was just struggling with a similar problem with pipenv that was giving me the same error messages.
WinError 2 has to do with corrupted files in one of your Python installs/uninstalls. I searched regedit for Anaconda3 to figure out which version of Python that I had previously installed or uninstalled was causing the problem.
For me, it was Python 3.6.5. I installed it in the same location as the path in the error message (in your case that would be D:/program_files/). Then, I just uninstalled it with the installation exe, and I stopped getting these error messages.
Have you tried the conda install command? To do this, go on your anaconda prompt, cd in the folder where you have installed your anaconda. Have a look at this.
conda install -c conda-forge pipenv
make sure you activate your environment before running the conda install command. To activate your environment run conda activate envname. I hope it helps!

I tried to change the Kernel but I had only one Kernel called "Python3". I tried to remove it and created a new Kernel called "Python tensorflow1". I tried to run the codes with that Kernel and it still gives me that red error.
It also says Failed to start the Kernel.
Please activate the environment tensorflow1 and install ipykernel in that environment uing below commands:
conda activate tensorflow1
conda install ipykernel
ipython kernel install --name tensorflow1 --user
Then try to use access jupyter notebook using the below command:
jupyter notebook
If the above steps doesn't work please follow the below steps to create a new conda environment and access jupyter notebook from that environment:
conda create -n env_tf -c intel python=3.6
Once the conda environment is created successfully, you can list the environment using the below command:
conda env list
It should be listing :
D:\Anaconda\envs\env_tf
Activate the environment using the below command:
conda activate env_tf
Install ipykernel in the activated environment:
conda install ipykernel
ipython kernel install --name env_tf --user
Access jupyter notebook using below command:
jupyter notebook
Hope this helps.
I was installing pymc through conda, and it told me to update a few of the files so no problem. However, after updating, it gave an OSError, and now, I cannot access any conda build commands. Now, when I type any conda command, it gives me
-bash: conda: command not found
I checked the bash_profile, and .bashrc, and both have the appropriate PATH for conda, and most modules installed through conda still works. Running python and checking the version yields
Python 2.7.11 :: Anaconda custom (x86_64)
Looking at the ~/anaconda/bin, I see that the conda folder is not there. Is there anyway to fix this? Is the only solution to re-install anaconda?
Sorry, I do not have any of the terminal outputs since I closed all my windows. Also, I didn't realize I was running Jupyter notebook in the background, but this shouldn't have a problem. Jupyter no longer runs, and yields the error

Sorry, I'm just not entirely sure what is going on.

In answer to this, you can try overwriting your conda installation:
bash /path/to/Miniconda2-latest-MacOSX-x86_64.sh -bfp /Users/kaichang/anaconda/
