Conflicting requirements

[luisdamed]

When performing a fresh installation via pip install -r requirements.txt, i get the following error:

The conflict is caused by:
    The user requested urllib3==1.26.5
    requests 2.23.0 depends on urllib3!=1.25.0, !=1.25.1, <1.26 and >=1.21.1

I was able to complete the installation by modifying the requirements to

certifi==2020.4.5.2
chardet==3.0.4
idna==2.9
requests>=2.23.0
urllib3==1.26.5

Pip installed requests-2.28.1.

Expected behavior:
Running the command pip install -r requirements.txt will perform a complete installation with no conflicting libraries

Actual behavior:
Module requests 2.23.0 depends on urllib3!=1.25.0, !=1.25.1, <1.26 and >=1.21.1, while the original requirements is urllib3==1.26.5
