These services are authenticated using an access token acquired from your JupyterHub's user interface under /hub/token. SFTP server deployed alongside the JupyterHub's user storage, you can use SFTP to work against your JupyterHub user's home directory. With a JupyterHub SSH server deployed, you can start and access your JupyterHub user environment through SSH. I also tried to follow the suggestions referenced in this question, but to no benefit.Access through SSH any JupyterHub, regardless how it was deployed and easily transfer files through SFTP. Python3 /home/zuddler/anaconda3/lib/python3.8/site-packages/ipykernel/resources The executed commands and outputs are below, it revealed the default kernel: (base) cd /home/zuddler/anaconda3/share/jupyter/kernels/ The default often does what you want, so if the python3 kernelspec points somewhere else and you can’t start a Python kernel, try deleting or renaming that kernelspec folder to expose the default. I further tried to rename the kernel folder as mentioned in this jupyter-notebook docĪ path ending in ipykernel/resources, like in the example above, is this default kernel. To be sure that the kernel had the correct python path, I checked the kernel.json file, the path to python 3 was correct (base) cat /home/zuddler/anaconda3/share/jupyter/kernels/python3/kernel.json jupyter/jupyter_notebook_config.py file (as mentioned here), but it did not fix the issue. I also set c.NotebookApp.allow_remote_access = True in. home/zuddler/anaconda3/bin/jupyter-notebook To check if there is some path issue, I checked using which as mentioned here and it returned (base) which jupyter-notebook So, I tried to check if I have the lastest versions of conda and jupyter and it returned: (base) jupyter -version # All requested packages already installed.
SSH TUNNEL JUPYTER UPDATE
Tried updating jupyter using conda update jupyter, it returned (base) conda update jupyterĬollecting package metadata (current_repodata.json): done Kernel started: d6af7843-cf02-43ce-adc2-14a7659ee4ff, name: python3Īgain, upon executing jupyter kernelspec list, one kernel detail was returned (base) jupyter kernelspec list On clicking Set Kernel, it gave a connection failed error as belowīut again a kernel was started and the terminal showed the below line (similar to Jupyter Lab) Upon opening in the browser and starting the previously created python 3 notebook, it gave the error Kernel not found asked to select a kernel Upon running the command jupyter notebook -no-browser below is the terminal output: (base) jupyter notebook -no-browser Python3 /home/zuddler/anaconda3/share/jupyter/kernels/python3 Upon executing jupyter kernelspec list, one kernel detail was returned (base) jupyter kernelspec list Upon selecting the marked kernel, it gives the same error mentioned in screenshot 2. Which is also evident from the below screenshot Upon selecting the kernel Python 3, it says **Error Starting Kernel**īut a kernel was started and the terminal showed the below line Upon opening in the browser and starting a python 3 notebook, it asked to select a kernel Use Control-C to stop this server and shut down all kernels (twice to skip confirmation). Serving notebooks from local directory: /home/zuddler JupyterLab application directory is /home/zuddler/anaconda3/share/jupyter/lab JupyterLab extension loaded from /home/zuddler/anaconda3/lib/python3.8/site-packages/jupyterlab Upon running the command jupyter lab -no-browser below is the terminal output: (base) jupyter lab -no-browser But when I am not tunneling and accessing them using IP, the following errors occur. When I connect to Jupyter Lab or Jupyter Notebook using ssh tunneling ssh -N -f -L localhost:8889:localhost:8888 and access localhost:8889 everything works fine. Start Jupyter Lab using jupyter lab -no-browser or Start Jupyter Notebook using jupyter notebook -no-browserĪnd access the Jupyter Lab/ Jupyter Notebook from my computer using gedit /home/koushik/.jupyter/jupyter_notebook_config.py and edit the values c.NotebookApp.allow_origin = '*' and I set up the Jupyter Notebook/ Jupyter Lab to be accessed remotely using the method provided in this answer (IP of that computer is 172.17.25.75), I've quoted the steps below:
SSH TUNNEL JUPYTER INSTALL
I am using a fresh Anaconda 3 install in Ubuntu 20.04 LTS. Any solutions, suggestions, or directions are greatly welcomed. I am getting a problem in opening remote Jupyter Lab/ Jupyter Notebook, it is not connecting to the kernel, I've mentioned the setup steps, problem coming and attempted fixed below.
