Describe the problem

Trying to install the requirements on an Ubuntu system but get an error:

Source code / logs

Include any logs or source code that would be helpful to diagnose the problem. If including tracebacks, please include the full traceback. Large logs and files should be attached. Try to provide a reproducible test case that is the bare minimum necessary to generate the problem.

Hi itemko, Sorry, for our testing, we always install TF first which will use numpy. We can add numpy to the dependency. Would you like to send a PR? Thanks!

@yeqingli , + Yeqing, could you verify this?

Hi itemko,

Thanks for the sending this. I have reproduced on my side. This issue is because the pip doesn't install the packages in the order of requirements. I will send out a fix.

[yeqingli]

An easy fix would be first install a Tensorflow library first and then run the pip install the requirements. Because the TF will install numpy first, it should fix the problem.
