The kernel appears to have died. It will restart automatically

I use “minimal-notebook” as a base and install some extra packages, like “anndata” and “matplotlib”.

Then, I start the docker by

docker run -m 8g --memory-swap="20g"  --cpus=2 -e NB_USER=jovyan -w /home/jovyan -v /Users/me:/home/jovyan/work -p 8888:8888 -it minimal-notebook_extra:latest

Then I enter Jupyter Notebook and import a library

import anndata as ad

It works well. Then I try to load my data

adata = ad.read("mydata.h5ad")

Then it reports an error

Kernel Restarting
The kernel appears to have died. It will restart automatically.

Without Docker, I could load the data normally. Does anybody have an idea what causes this error?

Have you checked the docker logs to see what the logs show? It might have some helpful information.
