I am running into the following error when building keras-2.7.0:

Doing a search for that error seems to indicate that there is a mismatch with protobuf, but I have ensured that the protobuf library and python protobuf are at the same version, 3.17.3. I have tried different versions of protobuf as well but keep hitting the same error. Could it be a mismatch of some sort between keras and tensorflow, as it seems to be failing on a tensorflow module? The same versions of protobuf are being used for both tensorflow and keras.
Thanks.
