This is not a build error, but an error on first import: as shown in report. It does not occur in tensorflow-2.3.0, so I install that with pip to get tf working on a mac.

I have exactly the same problem on macOS 10.15.17. I tried rebuilding tensorflow locally (using "port install -s") but to no avail. Is there any additional information I can provide to help fix this?

Same issue with the latest bazel PG and py-tensorflow Portfile.

see e.g. https://github.com/tensorflow/tensorflow/issues/41682

might be fixable with a small patch. Let me try.
