Errors when trying to use Python autotranslation in JVM kernels

When I try to execute any cell containing `%%python` in a JVM-based notebook, the following error is thrown and displayed as an output:

```
py4j.Py4JException: An exception was raised by the Python Proxy. Return Message: Traceback (most recent call last):

```

The error happens on installation made either from cloned repos (i.e. like `cd beakerx_kernel_groovy/groovy-dist; pip install -r requirements.txt --verbose; beakerx_kernel_groovy install`) or from published packages (i.e. `conda install -n beakerx -c beakerx beakerx_all`).

I also have an old installation laying around made from Github cloned repos on 2020-11-06, where the error doesn't occur.
