I wrote the cilf file and cpp file, but I can't import this file,
do I need to compile it？, how to link python and C++？

from third_party.nucleus.io.python import tfrecord_reader ImportError: cannot import name 'tfrecord_reader' from 'third_party.nucleus.io.python'

@pichuan does nucleus have support for building user-provided .clif extensions?

Thanks @rwgk for tagging me!

The Nucleus BUILD file for clif is here: https://github.com/google/nucleus/blob/v0.6.0/nucleus/util/python/BUILD

@one-matrix , if you're able to build Nucleus (or DeepVariant repo) before any changes, then, after you add your new files, and your own corresponding BUILD rules, you can try to build again.

Also note that the latest released Nucleus code is in https://github.com/google/deepvariant/tree/r1.6/third_party/nucleus . We used to make standalone Nucleus releases, but in recent years we focused more on making it as part of DeepVariant.
