AttributeError: module 'tensorflow._api.v1.summary' has no attribute 'create_file_writer'

[mtwenzel]

Thank you very much for reporting a bug on Talos. Before you do, please go through the below checklist carefully and make sure to prepare your bug report in a way that facilitates effective handling of the matter.

1) Confirm the below

• [x] My Python version is 3.5 or higher
• [x] I have searched through the issues Issues for a duplicate
• [x] I've tested that my Keras model works as a stand-alone

2) Include the output of:

talos.__version__ 0.6.3

3) Explain clearly what you expect to happen

Tune one hyperparameter.

4) Explain what actually happened

Error:

5) Provide a code-complete reference

Don't think it will help. Error is supposedly related to version incompatibility, as all code runs fine without talos.

Welcome to Talos community! Thanks so much for creating your first issue :)

Solved. TF 2.0.0 rc0 works. My notebook didn't use it, though, which I didn't notice.
