### Solution

Step 1. Downgrade your notebook to 5.5.0
In the `Dockerfile` add these line at the end of Dockerfile
```
pip uninstall notebook
pip install notebook==5.5.0
```
Note: even notebook version 5.6.0 did not work in this case.

Step 2. in the `requirements.txt`, add `jupyterlab` after `jupyter`

Step 3. Build your `geo-ml-docker` docker images with `docker build -t geo-ml-docker .`
