requirements.txt is broken

Thank you @Geoyi, it solved my problem!

@chelm, pretty cool that you tried it out and filed the first issue ever on this repo. I fixed the dependencies on requirement.txt, do you want to give another try?

Hello,

Thanks for sharing your project!

I still got conflict versions with the update of requirements.txt
Here are the bugs I met:

• Conflicting versions of decorator

  pkg_resources.ContextualVersionConflict: (decorator 4.1.2 (/usr/local/lib/python3.6/dist-packages), Requirement.parse('decorator>=4.3.0'), {'networkx'})
  

  fixed by upgrading decorator to 4.3.0 and changing the corresponding line in requirements.txt

• Missing packages

  ModuleNotFoundError: No module named 'tensorflow'
  

  and

  ModuleNotFoundError: No module named 'cv2'
  

  so I installed tensorflow and opencv-python

• I was using Keras 2.2.2 but

  from keras.applications.imagenet_utils import _obtain_input_shape
  ImportError: cannot import name '_obtain_input_shape'
  

  I turned keras.applications.imagenet_utils to keras_applications.imagenet_utils, it seems to do the trick.
  There are also conflicts with tensorflow 1.11.0:

  keras 2.2.2 has requirement keras-applications==1.0.4, but you'll have keras-applications 1.0.5 which is incompatible.
  keras 2.2.2 has requirement keras-preprocessing==1.0.2, but you'll have keras-preprocessing 1.0.3 which is incompatible.
  

  So I downgraded tensorflow to version 1.10.0

I was then able to start the training. But I got another error then... I'm not sure if it's from the changes I made or something else. It happens when it will start the 1st epoch training. Here is the complete error, tell me whether it worth opening a new issue:

@paumillet, thanks for posting the issue.
Can you make a pull request to the requirement.txt on what you've installed for tensorflow and opencv-python?
The error you got was from the label data, and you may want to look into another issue, I posted a solution there. Hope that is helpful if you keep getting error, let me know.
