mportError: /vid2vid/models/flownet2_pytorch/networks/resample2d_package/_ext/resample2d/_resample2d.so: undefined symbol: PyInt_FromLong

I run this command

python3 test.py --name label2city_2048 --loadSize 2048 --n_scales_spatial 3 --use_instance --fg --use_single_G

And got this error:

/usr/lib/python3.5/importlib/_bootstrap.py:222: RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88
  return f(*args, **kwds)

Why？How?

It looks like flownet2 wasn't compiled successfully. Please refer to https://github.com/NVIDIA/flownet2-pytorch/issues to see if there are similar issues.

I use the python36 branch of https://github.com/NVIDIA/flownet2-pytorch ,and the error was solved . But the new one is occurs below:

This error should be solved by using pyTorch >= 0.4.
