Hi Samuel, I have try to add Python3.7 kernel, as followed ``` [root@master ~]# python3.7 -m ipykernel install --name 'Python37' Installed kernelspec Python37 in /usr/local/share/jupyter/kernels/python37 [root@master ~]# jupyter-kernelspec list Available kernels: ir /root/.local/share/jupyter/kernels/ir java /share/apps/platform/ai/py36/3_6_9/share/jupyter/kernels/java python3 /share/apps/platform/ai/py36/3_6_9/share/jupyter/kernels/python3 python37 /usr/local/share/jupyter/kernels/python37 [root@master ~]# ```
Now, i have opened jupyter browser and check the kernels and seen the below notebooks However, when i run the Python3 notebook,check the version,it showing my python version as python 3.6.9 [image: image] Then i run the Pyhton37 notebook, check the version, [image: image] it is getting error as No Kernel!! [image: image] Finally i check the jupyterhub logs ``` Aug 17 21:37:28 master jupyterhub: [I 2020-08-17 21:37:28.767 SingleUserNotebookApp restarter:110] KernelRestarter: restarting kernel (2/5), new random ports Aug 17 21:37:28 master jupyterhub: /share/apps/platform/ai/py37/3_7_6/bin/python3.7: error while loading shared libraries: libpython3.7m.so.1.0: cannot open sha red object file: No such file or directory Aug 17 21:37:29 master jupyterhub: [I 2020-08-17 21:37:29.557 SingleUserNotebookApp log:174] 200 GET /user/zain/api/terminals?1597680450116 ([email protected]) 8.74ms Aug 17 21:37:31 master jupyterhub: [I 2020-08-17 21:37:31.791 SingleUserNotebookApp restarter:110] KernelRestarter: restarting kernel (3/5), new random ports Aug 17 21:37:31 master jupyterhub: /share/apps/platform/ai/py37/3_7_6/bin/python3.7: error while loading shared libraries: libpython3.7m.so.1.0: cannot open sha red object file: No such file or directory Aug 17 21:37:32 master jupyterhub: [I 2020-08-17 21:37:32.608 SingleUserNotebookApp log:174] 200 GET /user/zain/api/contents/?content=1&1597680453144 (zain@192. 168.43.8) 30.67ms Aug 17 21:37:32 master jupyterhub: [I 2020-08-17 21:37:32.813 SingleUserNotebookApp log:174] 200 GET /user/zain/api/sessions?1597680453366 ([email protected]) 7 .15ms Aug 17 21:37:32 master jupyterhub: [I 2020-08-17 21:37:32.866 SingleUserNotebookApp log:174] 200 GET /user/zain/api/kernels?1597680453435 ([email protected]) 3. 78ms Aug 17 21:37:33 master jupyterhub: [I 2020-08-17 21:37:33.212 SingleUserNotebookApp log:174] 200 GET /user/zain/metrics?1597680453751 ([email protected]) 28.86m s Aug 17 21:37:33 master jupyterhub: [I 2020-08-17 21:37:33.343 SingleUserNotebookApp log:174] 200 GET /user/zain/metrics?1597680453875 ([email protected]) 31.66m s Aug 17 21:37:34 master jupyterhub: [I 2020-08-17 21:37:34.815 SingleUserNotebookApp restarter:110] KernelRestarter: restarting kernel (4/5), new random ports Aug 17 21:37:34 master jupyterhub: /share/apps/platform/ai/py37/3_7_6/bin/python3.7: error while loading shared libraries: libpython3.7m.so.1.0: cannot open sha red object file: No such file or directory Aug 17 21:37:37 master jupyterhub: [W 2020-08-17 21:37:37.836 SingleUserNotebookApp restarter:100] KernelRestarter: restart failed Aug 17 21:37:37 master jupyterhub: [W 2020-08-17 21:37:37.837 SingleUserNotebookApp kernelmanager:135] Kernel 448a56bf-42a3-4718-a126-26f5cf5c0d37 died, removin g from map.
