When web service(jupyter lab) can not start, please check the following points.
check the log and investigate what is happening
Output files of web services are saved under ~/.t3was/.
There might be some hints in the files.
Initialize the environment
Initialize python 3.6 environment such as moving ~/.local/lib/python3.6/ to another directory, and then do
| $ python3 -m pip install --user (modulename) |
module conflict might be solved.
if web service was able to start by doing this, install some necessary modules from the jupyter lab console, and then
| $ python3 -m pip check |
this checks the dependencies and update problematic modules by doing
| $ python3 -m pip install -U --user (modulename) |
, the problem can be solved.
Check and resolve module dependencies, avoiding initialization of the environment
This is almost the same as the abobe, after SSH'ing to TSUBAME, do
| $ module load jupyterlab/3.0.9 |
then the environment of Jupyter Lab in the web service is loaded.(3.0.9 is necessary)
After this, execute
| $ python3 -m pip check |
and check if there is problematic modules in the dependencies.
If there is, do
| $ python3 -m pip install -U --user (modulename) |
and update them.
