I also met this error in some environment, it seems that some python dependency makes the compiling failed, I solved it by creating a new conda environment and install dependencies as described in README. Could you try to create a new environment and try again? Thanks!

Also, you can try the new requirements.txt that I just updated.

@wangshuwch I only test the code under Ubuntu 16.04.

from vl-bert.

I have the same issue with this. Does anyone figure out what is the problem?

from vl-bert.

In my case, I resolved this by upgrading gcc 4.9.3 to 5.4.0 :)

And, I don't know why roi_pooling successfully built using "./scripts/init.sh" instead of building in the exact directory.

from vl-bert.

@becxer Actually in the './scripts/init.sh', it would enter the directory firstly and then compile the operators.

@jackroos Yes I know... it sounds weird but doing it manually gives the same error :(
