Jupyter notebook works but Jupyterlab gives blank page on gpu image

[NahsiN]

🐛 Bug

Accessing the Jupyter lab UI is not working on the GPU docker image.

To Reproduce

1. docker run -p 8888:8888 --runtime nvidia --rm -it gcr.io/kaggle-gpu-images/python /bin/bash
2. Run jupyter lab --allow-root --ip 0.0.0.0 In the interactive terminal
3. Access url http://127.0.0.1:8888/lab?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx gives a blank page
4. But running jupyter notebook --allow-root --ip 0.0.0.0 does work

Expected behavior

The Jupyterlab UI works.

Okay, since this image is now based on Google Colab #1444, I used [1,2] to connect the local runtime to Google Colab

1. docker run -p 127.0.0.1:9000:8080 --runtime nvidia --rm -it gcr.io/kaggle-gpu-images/python /bin/bash
2. Run /datalab/run.sh and take note of the url shown in stdout http://127.0.0.1:9000/?token=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
3. Go to https://colab.research.google.com/ Open a new notebook, select connect to local runtime and past the url in the previous step
