Pypi Installer issue

[EncinasAlar]

Hi, I'm having an issue.
When I try to install histocartography with pip I get the following error:

ERROR: Could not find a version that satisfies the requirement dgl==0.4.3.post2 (from histocartography) (from versions: 0.9.0, 0.9.1, 1.0.0, 1.0.1, 1.1.0, 1.1.1, 1.1.2, 1.1.2.post1, 1.1.3, 2.0.0)
ERROR: No matching distribution found for dgl==0.4.3.post2

Also, I was wondering I you could be able to specify the versions of the packages used in the requirements.txt file to be able to install it properly.

Thank you.
