I've only gotten Linux CST 2020.0/.04 to work with the provided python3.6.0 environment. I've tried a 3.6.0 environment from conda forge with no luck. I notice that the provided python environment already has the cst package. Maybe the cst package in the provided environment is working but the package in python_cst_libraries doesn't work.

Below is the error with 3.6.0. I get the same error with 3.6.10. This code runs without error on the provided 3.6.0 environment.
