I am finding the error after installing QMLT in my ubuntu 18.04.

This appears to be happening at the import line, i.e., before any meaningful code is run. This suggests to me that it is probably a problem/conflict within your current install. Could you try installing these packages in a clean virtual environment (e.g., anaconda), and see if you still receive the error?

also, @josh146 what are your thoughts?

josh146 commented 5 years ago

Very odd, it seems to be an issue with NumPy as well. @co9olguy I agree, it looks like @Ayushprasad28 you may need to try again in a fresh Python environment.

Thank you @co9olguy and @josh146 . It seems like there was some issue with my ubuntu Python environment. After reinstalling to a fresh environment it worked without any issue.
