tensorflow: import tf fails in "imp.find_module('_pywrap_tensorflow_internal',"

I get error below trying to import TensorFlow built at commit 7e9f2dc (head as of Sat 4).

I haven’t made any changes to my build procedure in last month, and installing similarly built wheel from Mar 1 works.

Looking at relevant differences between Mar 1 and Mar 4 I see that @jhseu 's 718812c refactored Python module loading in https://github.com/tensorflow/tensorflow/blob/b10f50ff15944badb7262a207f6628dfa52d6a9d/tensorflow/python/pywrap_tensorflow.py

make sure you aren’t getting this error as a result of running python from the actual git directory where you downloaded tensorflow.

if you’re following the step-by-step install from the documentation page, and get to the final step where you verify the install, you start python from the terminal and run ‘import tensorflow’, and you would get this error. go to any other directory and you’re fine.

This 1.0.0 build was such a pain! After way more time that I wanted to on this, I got something that works on MacOS.

First I had to deal with a Mac-specific issue where a protection scheme, SIP, prevents you from defining DYLD_ anything in env, so it could not find libcudart.8.0.dylib. This dude blogged a workaround - https://srikanthpagadala.github.io/notes/2016/11/07/enable-gpu-support-for-tensorflow-on-macos
Then I ran into an issue where it could not find another library, libcublas. Since I used Homebrew (as per all guidance everywhere) to get bazel, it got 0.4.4 which doesn’t work with this source. Someone posted on this issue how to roll back to 0.4.3 - https://github.com/tensorflow/tensorflow/issues/7227
Finally, the problem you are all having here. After finally getting the build and installing the wheel in my conda env, I ran into an error trying to find pywrap_tensorflow_internal.so when I ran the interpreter and tried to import tensorflow. Turns out the wheel had one error while being assembled. I looked at the conda env site packages to see if the .so is actually there. It was, but it was named _pywrap_tensorflow_internal.so (notice the initial underscore). I removed the underscore by hand and it finally worked. 😕 This last bit might help you guys on Linux maybe?
