ImportError: Could not find BlenderBot 3

[notBradPitt]

I'm having trouble importing BB3 model using Colab. I've tried several names but none of them work, even simple commands like parlai interactive --model-file "zoo:bb3/bb3_3B/model" still returns an error.

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/dist-packages/parlai/core/build_data.py", line 490, in modelzoo_path
    my_module = importlib.import_module(module_name)

During handling of the above exception, another exception occurred:

Do you have the most recent version of ParlAI?

[notBradPitt]

Yes. I don't think Colab has them pre-installed on their machine, so I tried using both pip and from the repo

It seems to me that the latest version of parlai needs python 3.8 while colab (in its standard setup) comes with 3.7 which seems to indicates that you are not using the latest parlai version.
