Installation fails due to conflicting numpy version

[NeolithEra]

Hi, users are unable to run CBGT due to dependency conflict with numpy package. As shown in the following full dependency graph of CBGT, CBGT requires numpy==1.11.3，while seaborn>=0.5.1 requires numpy>1.11.3.

According to pip’s “first found wins” installation strategy, numpy 1.11.3 is the actually installed version. However, numpy 1.11.3 does not satisfy numpy>1.11.3.

Dependency tree-----------

CBGT - 0.0.6
| +- future(install version:0.18.2 version range:*)
| +- matplotlib(install version:3.2.1 version range:>=1.4.3)
| | +- cycler(install version:0.10.0 version range:>=0.10)
| | | +- six(install version:1.14.0 version range:*)
| | +- kiwisolver(install version:1.2.0 version range:>=1.0.1)

| | +- python-dateutil(install version:2.8.1 version range:>=2.1)

| | +- pandas(install version:1.0.3 version range:>=0.22.0)
| | +- scipy(install version:1.2.3 version range:>=1.0.1)

Thanks for your help.
Best,

Solution

1. Loosen the version range of numpy to be >=1.11.3.
2. Remove your direct dependency numpy, and use the numpy transitively introduced by seaborn.
   @clappm Which solution do you prefer, 1 or 2?

Hi @NeolithEra I'm sorry but I'm no longer actively contributing/supporting to this project or the repo. @clappm can you weigh in on this?
