installation: issue with gast, tensorflow

[emsal0]

Starting up in a new virtualenv with Python 3.7.5 (arch linux)

(had to run sudo otherwise setup.py gives a permission denied)

Get this as the final error: error: gast 0.2.2 is installed but gast>=0.3.2 is required by {'tensorflow-probability'}

It seems there might be a dependency here that's underspecified (maybe tensorflow version is too high)

[jschwan2]

Currently have the same issue. Any fixes?

[emsal0]

I had some mileage by using pip's new 2020 resolver. Activate by upgrading pip to the latest version and setting the flag --use-feature=2020-resolver.

[jschwan2]

Thanks! The flag helped but now I'm receiving Illegal instruction when I import pilco. Is this happening for you?

[emsal0]

Sorry for the late response, and sorry again that I'm not able to replicate that problem. I think there might be some work that needs to be done specifically for compatibility with GPflow 2.1, however

[Pengxiao-Gao]

Hello, i have also the same issue. Have you solved this problem?

[nrontsis]

I think that this has now been resolved. Feel free to reopen if you think it hasn't.
