ModuleNotFoundError after installation

[ntomita]

Hi Peter,

I got a ModuleNotFoundError when importing staintools. Here's the traceback:

Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
  File "/lib/python3.6/site-packages/staintools/__init__.py", line 1, in <module>
    from .stain_extractors.macenko_stain_extractor import MacenkoStainExtractor
ModuleNotFoundError: No module named 'staintools.stain_extractors'

I installed staintools via pip on Ubuntu16.04 with python 3.6. I installed the required library as well. Do you have any idea why this happens and how to make it work properly?

Same here, on ubuntu 16.04, python 3.5.

1. After installing staintools from pip, I could not find the stain_extractors directory in the package directory. Terminal screen for demonstration:

   scorbie@scorbie-laptop /usr/local/lib/python3.5/dist-packages/staintools
   $ ls
   __init__.py  reinhard_color_normalizer.py  stain_normalizer.py
   __pycache__  stain_augmentor.py            utils

2. On setup.py, line 14 setuptools.find_packages() is used.

3. Browsing the setuptools documentation, it seems like find_packages() only recognizes packages that contain __init__.py, which only stain_extractors does not have.

Thus, I think a simple fix of adding __init__.py to the stain_extractors directory may solve the issue. I'll test it and send you a pull request if it works.

Edit: That worked. Am writing a pull request right now. Until the change gets on its way, one can manually apply the change by manually copying the missing folders and files from Github.

Awesome, thanks! @Scorbie

Yes sorry not sure how I missed that init file
