How do you manage conflicting packages in your requirements.txt ?
Hi,

Let's say you have in your requirements.txt :

    package_A
    package_B
    package_C
    package_D

but `package_A` requires `some_dependency&lt;=1.5` and `package_B` requires `some_dependency&gt;=2.2` . How do you handle that (knowing that I might have tens of conflicting packages)?

I don't think virtualenvs would be a good solution here since the project has one entry point and packages are imported in the same code ...

Thank you !:)
