Only Apple's Tensorflow: Segmentation fault 11 / Abort trap 6 when running KataGo's training loop #258

Hi. I have upgraded the source code of KataGo (a Go-playing program, github.com/lightvector/KataGo) to Tensorflow 2, and the resulting code (github.com/MarkTakken/KataGoTF2MacOS) works fine with the official Tensorflow 2.4.0. However, when I try to run the training loop with Apple's Tensorflow, I get a "Segmentation fault: 11" or occasionally an "Abort trap: 6" error. You can recreate the error by running the following in the terminal (which will run smoothly with the official Tensorflow but crash with Apple's Tensorflow):

git clone https://github.com/MarkTakken/KataGoTF2MacOS.git cd KataGoTF2MacOS python/selfplay/train.sh TestRun testruntraining b6c96 128 trainonly

I have also found that the error is thrown in line 725 of train.py, that is, when the actual training begins. As this appears to be an issue solely with tensorflow_macos, I would greatly appreciate it if you could help identify and fix the problem. Thank you in advance.

P.S. The test data (produced from selfplay) that this trains on is at TestRun/shuffleddata/current/train/data0.tfrecord.
