[enformer] enformer-training.ipynb failed to get dataset

Hi,

I am trying to run the notebooks provided by the author within the enformer package. However, I faced CA certification problem while running this line:
`human_dataset = get_dataset('human', 'train').batch(1).repeat()`

The error message is
`FailedPreconditionError: Error executing an HTTP request: libcurl code 77 meaning 'Problem with the SSL CA cert (path? access rights?)', error details: error setting certificate verify locations:
CAfile: /etc/ssl/certs/ca-certificates.crt
CApath: none
when reading metadata of gs://basenji_barnyard/data/human/statistics.json`

Do you know how can I solve this?
