Problem description

Previously, rename a CONDA virtual environment with the following command:

conda create -n torch --clone rl
conda remove -n rl --all

Then start jupyter from Torch virtual environment, and the following error is reported:

Fatal error in launcher: Unable to create process using
"g:\miniconda3\envs\rl\python.exe"
 "G:\miniconda3\envs\torch\Scripts\jupyter-notebook.EXE"

Reference solutions

I checked the online information and found that it was better after a mess… So I’m not sure which operation fixed the problem. What’s more certain is the last few executed commands:

pip uninstall ipython
pip uninstall jupyter
pip uninstall notebook

Or (after the above command is executed, try installing jupyter first. If the problem cannot be solved, execute the following command)

pip install pip-autoremove
pip-autoremove jupyter -y

Then install jupyter

pip install jupter
