Hi, @ohosseini

I met this error when run install.sh in my ubuntu19.10.

kerbal@msi:~/Desktop/DOCS-pytorch$ ./install.sh

What's wrong to me ?

Thanks.
Best,
@bemoregt.

when i run the order, "bash demo.sh " in the terminator, there will be a error as following

/home/mpl/anaconda3/lib/python3.6/importlib/_bootstrap.py:219: RuntimeWarning: numpy.dtype size changed, may indicate binary incompatibility. Expected 96, got 88
return f(*args, **kwds)

and i have check, under the path, there exactly exist the correlation_cuda.cpython-36m-x86_64-linux-gnu.so file. and i have add the path /home/mpl/.local/lib to the ~/.bashrc file. Thanks for your reply
