Log instead of print messages

[radomirbosak]

For code that is using pytorch2timeloop-converter it is sometimes undesirable to have text printed in stdout.

This package prints messages like

converting nn.Conv2d and nn.Linear in out model ...

on around four places, e.g.

pytorch2timeloop-converter/pytorch2timeloop/converter_pytorch.py

Line 52 in 1e36aa5

print("converting {} in {} model ...".format("nn.Conv2d" if not convert_fc else "nn.Conv2d and nn.Linear", model_name))

A good mechanism for these kind of message is using the logging module, which can be turned on and off quite easily.

Other print statements found:

$ git grep -n 'print('
pytorch2timeloop/converter_pytorch.py:28:    print("converting {} in {} model ...".format("all", model_name))
pytorch2timeloop/converter_pytorch.py:52:    print("converting {} in {} model ...".format("nn.Conv2d" if not convert_fc else "nn.Conv2d and nn.Linear", model_name))
pytorch2timeloop/converter_pytorch.py:113:    print("conversion complete!\n")
pytorch2timeloop/utils/hooks.py:228:    print("unknown module type", module.__class__)
