Yes it looks like 3.8 changes ast.Ellipsis to ast.Constant with `node.value is Ellipsis`.

I got the same error message.

Additionally, now I'm using

tensorflow-gpu==2.0.0-rc0
tensorflow-probability==0.8.0rc0

[brianwa84]

Try setting the version for gast==0.3.0 https://pypi.org/project/gast/#history

gast==0.3.0 doesn't fix this for me, but gast==0.2.2 does.

[awav]

@brianwa84 , gast==0.3.0 doesn't work, with 0.2.2 the TFP import works fine.

[janosh]

I'm still running into this issue with the latest nightly (tfp-nightly-0.9.0.dev20191008) which installs gast-0.3.2 for me in a clean environment.

[brianwa84]

tfp nightly works against tf nightly. Which version of TF are you using? Brian Patton | Software Engineer | bjp@google.com

Ah, sorry for the noise. I was still using tf-nightly-2.0-preview. Installing tf-nightly==2.1.0.dev20191008 solved the issue.
