Running Jupyter (v. 1.0.0) on a Linux server, with anaconda3 (v. 2019.07) 64-bit.
Available Kernels
Available kernels:
python3 /home/djan/.local/share/jupyter/kernels/python3
nn /home/djan/.local/share/jupyter/kernels/nn
Reproducing the issue
- Install the newest anaconda3 version.
- Run Jupyter notebook in the base version --> Kernel runs fine
- Create a new environment with python:
conda create -n test python=3.7 - After activating the environment, Jupyter notebook is not available, thus I must install it via Conda:
conda install -c anaconda jupyter - Run Jupyter notebook in the test environment --> Kernel breaks down as explained above
What I tried so far
There seems to be an issue with file permissions when running Jupyter on a server inside a Conda environment. I tried to give all files inside my anaconda3 folder the requested permissions (0600), but this did not help.
