Import error caused by some conflict with tensorflow

[CMCDragonkai]

I found this weird error with imgaug 0.4.0 and tf 1.15.0.

import tensorflow as tf
import imgaug

Gives me:

But if I do the other way around:

import imgaug 
import tensorflow as tf

It works as advertised!

Is there some conflict between tensorflow and imgaug in how they use opencv? This conflict leaks through the imports... really annoying.

Hm, weird error. I'm not aware of any incompatibilities with respect to OpenCV. There are similar errors here: https://github.com/lhelontra/tensorflow-on-arm/issues/13 and here: https://github.com/ContinuumIO/anaconda-issues/issues/483 . Maybe one of the suggestions helps?

Which package manager did you use for the installations? Does /nix mean that you use NixOS?

Yes I'm using NixOS. But I'm just changing the import order to avoid this problem.

This seems to apply where you need to import cv2 ahead of tensorflow as well.

import cv2
import tensorflow as tf

Because of:
