Bug 682212 – sci-libs/tensorflow-1.13.0_rc2 with media-libs/opencv-3.4.1-r5 - python module conflicts over "tensorflow.AttrValue" protobuf symbol

• Product: Gentoo Linux
• Status: RESOLVED FIXED

(same results in python2.7 and python3.6)

While I could find very little info on google that seemed pertinent, https://stackoverflow.com/questions/51795326/static-linking-of-protocol-buffers-results-in-conflicts-with-existing-symbols?rq=1 may be relevant, and https://github.com/tensorflow/tensorflow/issues/9525 might be tangentially related.

This https://github.com/tensorflow/tensorflow/pull/19966 seems relevant.

same here. No changes for tensorflow-1.13.1. I've tested protobuf-3.7.1 and 3.6.1.3: no difference between them. That patch, mentioned by Amy Liffey is present (at least in ./tensorflow/BUILD) - but something's going on behind the scenes. :-(

Created attachment 591018 [details, diff]
Rename tensorflow namespace patch

I found the fix finally: 
https://github.com/opencv/opencv/pull/10092
https://github.com/opencv/opencv/commit/cb5da8983f911002ba8a316695c634111a62d274
Applying that commit to opencv fixes it for me. The fix is in opencv-3.4.4, so best is just to bump the package, there are several new versions that are not yet in the tree.

The patch does not apply as-is, ive attached the fixed patched which works when put in epatch_user

[Comment 4 Michael Moon 2019-10-04 11:10:46 UTC]

Works for me, thanks!

[Comment 5 kfm 2020-08-12 11:37:03 UTC]

All versions of opencv lower than 3.4.4 have been removed. Presumably, this bug can be marked as resolved.

[Comment 6 kfm 2020-09-03 11:08:01 UTC]

I am taking the liberty of closing this, per the prior comment and because tensorflow-1.x is no longer available in the gentoo repo. Hope that's OK.
