probability 0.17.0 doesn't build on macOS with error ModuleNotFoundError: No module named 'absl'

[essandess]

I'm attempting to update tensor flow_probability for MacPorts.

Version 0.17.0 fails to build on macOS with error:

File "/opt/local/var/macports/build/_opt_local_ports_python_py-tensorflow-probability/py310-tensorflow-probability/work/bazel_build/4191c7127d7c33c5af5f12aa8dc0d886/sandbox/processwrapper-sandbox/5/execroot/tensorflow_probability/bazel-out/darwin-opt-exec-2B5CBBC6/bin/tensorflow_probability/substrates/meta/rewrite.runfiles/tensorflow_probability/tensorflow_probability/substrates/meta/rewrite.py", line 20, in <module>
from absl import app
ModuleNotFoundError: No module named 'absl'

(Full log file: main.log.gz)

This import issue may be caused by the fact that there is no __init__.py file in the directory ./tensorflow_probability/substrates/meta.

I've tried adding my own __init__.py file to the source directory, but bazel appears to be downloading its own source, and I'm uncertain how to address or work around this issue.

See also #539.

I tried to install to install tensorflow from source using the following command:

bazelisk build --copt=O3 --copt=-march-native :pip_pkg

I also get, on ubuntu, the same error:

ModuleNotFoundError: No module named 'absl'

I do not know how all this fits in MacPorts, but this is what I get from source with Ubuntu.

I have the absl module installed from the source abseil-py git repository. In a pyenv virtual environment. It seems bazel doesn't pick up the pyenv virtual environment infrastructure.

So. Two paths: 1. random tinkering till it works 2. getting into the nitty gritty of bazel.
