Issue: render_plot won't render,  getting 404 on GET /static/tensorflow_model-analysis.js?v=2020103020382
Root cause: Environment Incompatibility

I'm not getting tfma.view.render_plot to render plots with:


`tfma.view.render_plot(result)
`
or
`
tfma.view.render_time_series
`
No output to the cell appears other than 
`
Error rendering Jupyter widget: missing widget manager
`

note that `tfma.view.render_slicing_metrics` does work..

I suspect it's related to this 404... I'm getting the following error in jupyter notebook stdout log:

`[W 20:42:09.329 NotebookApp] 404 GET /static/tensorflow_model-analysis.js?v=20201030203829 (192.168.112.1) 14.49ms referer=http://localhost:18888/notebooks/analysis.ipynb
`

It seems relevant that the /static/tensorflow_model-analysis.js  file above in the 404 log  is not part of the package, as can be seen in the github repo itself:  [https://github.com/tensorflow/model-analysis/tree/master/tensorflow_model_analysis/static](https://github.com/tensorflow/model-analysis/tree/master/tensorflow_model_analysis/static)

this is running in a docker image from python:3.7-slim-buster (debian)

jupyter commands:
    
```
        /usr/local/airflow/.local/bin/jupyter nbextension enable --py widgetsnbextension --sys-prefix
        /usr/local/airflow/.local/bin/jupyter nbextension install --py --symlink tensorflow_model_analysis --sys-prefix
        /usr/local/airflow/.local/bin/jupyter nbextension enable --py tensorflow_model_analysis --sys-prefix
        /usr/local/airflow/.local/bin/jupyter nbextension install --py --symlink witwidget --sys-prefix
        /usr/local/airflow/.local/bin/jupyter nbextension enable witwidget --py  --sys-prefix

        /usr/local/airflow/.local/bin/jupyter nbextensions_configurator enable --user

        /usr/local/airflow/.local/bin/jupyter notebook --ip=0.0.0.0 --notebook-dir=/usr/local/airflow/dags --port=18888 

```

versions are:

 ```
cat requirements.txt | grep tensor

I tried tfma version 0.22.0 and had the same result, all else being equal.

i've found that if i wait long enough, the jupyter cell will return the following ressponse when running tfma.render_plot:

```
PlotViewer(config={'sliceName': 'Overall', 'metricKeys': {'calibrationPlot': {'metricName': 'calibrationHistog…
```

I'm happy to provide more info if needed.   Many Thanks.
