Please add 'test_requires' to setup.py

tests fail with:

ImportError: Failed to import test module: calculator_torch
...
ImportError: Failed to import test module: linear_regression
...
ImportError: Failed to import test module: model_torch
...
ImportError: Failed to import test module: nn

Hi @yurivict. How did you get these errors, via python setup.py test? These modules based on PyTorch are not needed for the current tests. Also, we use pytest in this project instead of unittest.

[yurivict]

python setup.py test prints these messages.

python setup.py test is deprecated:

$ python setup.py test
running test
WARNING: Testing via this command is deprecated and will be removed in a future version.

tests_require is also deprecated by setuptool. We'll add tests requirements to extras_require.

Then README needs to say how to run tests.
