Error thrown when trying to declare the GameInfo of a custom game

We are going to need more. Can you send us a link to the code, or copy it here? Did you start by copying an existing game?

[willmcgowan]

I copied the code provided in tic_tac_toe.py into a Jupyter notebook and got the error

Did you use pip to install OpenSpiel? If so, that will be why. We only added GameInfo recently, after the latest release used by the pip package.

[willmcgowan]

Yes I did use pip .

Ah yeah that won't work, the python game structure is too new. You will have to build from source or use the old python tic_tac_toe.py in the 0.2.0 release.

It would make sense to do a minor release to update the pip version since the recent python game overhaul. I will do it in the next few weeks, please leave the issue open for me as a reminder.

Just a quick update that I'm putting together a release in order to fix this. It necessitated a few other fixes (like #507 and 13c81e5), and I wrote a test script for the pip packages-- which caught said things :) ... anyway, it'll be large enough that we're going to stamp it as 0.3.0. So, if not next week then hopefully the week after.

Ok, we've put out a release: #512, which should fix this.

(You will need to uninstall your pip package and re-install it.)
