Hello Vanessa, In order to install POT with pip you need a c compiler on the machine (to compile the emd solver). You can install it on windows freely from the following url http://landinghub.visualstudio.com/visual-cpp-build-tools Still I'm surprised you cannot use conda since from the paths in the errors you are using an anaconda3 distributions that has conda installed by default.

Hi,
In the past, I have been able to successfully install the POT package using the conda installation tool, but now I'm trying to install the POT package in a cloud environment which doesn't allow me to use that.
I tried using "pip install" but it seems to be crashing because the C-library dependencies are missing. Below is the full error message. Has somebody else encountered this problem?
Thanks,
-Vanessa
