Comment # 2 on bug 1178287 from Guillaume GARDET

I tried to apply this upstream patch:
https://github.com/tensorflow/tensorflow/commit/f1a3ea4d5441f116dfa4083f7a60507bef4dfcfc

But it fails on the link with:

We should probably update Tensorflow2 to 2.3 or 2.4(-rcX).

@Christian, any ETA for an update?
