requirements handling

[visze]

I was wandering if pip already installs the requirements listed in the setup.py and you do not need to do the workaround with conda.

The conda workaround is for when you don't want to install the package via pip, otherwise pip should install the requirements.

I should probably explicitly mention this in the README.md

I think the environment.yml is not needed anymore. Maybe you can switch to a requirement file when using pypi, which make it easier with bioconda. But right now the recipe on bioconda works :-) https://bioconda.github.io/recipes/negative_training_sampler/README.html
