For some reason, the builder.py file is missing from the protobuf package created from TensorFlow. A workaround is to simply copy the latest copy of builder.py from the protobuf repository into your local drive

As mentioned above, dunno why protobuff 3.19.6 does not brings builder.py, so you just have to upgrade to to a higher version (lets say 4.21.1) copy builder.py and then downgrading to a tensorFlow compatible protobuff (in my case 3.19.6) and paste it. In my case I was using conda so, builder.py file location was:
