error when initializing the Geoparser

Hi

I get the following error when initializing the Geoparser:

Traceback (most recent call last):
File "", line 1, in
File "/Users/ZhendongLiu/Desktop/CSC440/Project/mordecai-env/lib/python3.6/site-packages/mordecai/geoparse.py", line 53, in init
self.country_model = keras.models.load_model(models_path + "country_model.h5")

return hdf5_format.load_model_from_hdf5(filepath, custom_objects, compile)
File "/Users/ZhendongLiu/Desktop/CSC440/Project/mordecai-env/lib/python3.6/site-packages/tensorflow/python/keras/saving/hdf5_format.py", line 176, in load_model_from_hdf5
model_config = json.loads(model_config.decode('utf-8'))
AttributeError: 'str' object has no attribute 'decode'

do you have any idea what's going on?

It look like the error is coming from trying to decode a string that's already decoded (Stackoverflow link). Mordecai only works with Python 3, so you shouldn't have to do any string encoding/decoding.

@ahalterman I am having the same issue as @ZhendongLiu while using python 3.7. Any idea what could be going on here? Or how to fix it?

[ahalterman]

This looks like a h5py and Keras incompatibility: tensorflow/tensorflow#44467. Changing the requirements file to h5py<3.0.0 should resolve it. I'll take a look over the weekend and push an update to pypi if that resolves it, but in the meantime, changing requirements.txt and installing from source should probably fix it (let me know either way!).

And @ZhendongLiu, I missed that you were using 3.6 already. Sorry about that.

As a workaround I installed an earlier version of h5py after installin mordecai from pip.

pip install -I h5py==2.10.0

The eiffel tower example works fine now.
