can't run demo, getting the following error: ImportError: You need to first <code

You need to first `import keras` in order to use `keras_preprocessing`. For instance, you can do: about textgenrnn HOT 2 OPEN

same here. running this via the tweet package and got this traceback:

Or, preferably, this equivalent formulation:

\```

any ideas how to resolve this?

edit: okay, updating tensor flow fixed that for me and then it turned into another issue #197 (for which a fix was provided fortunately)

Hi, I have spent quite a lot of time solving this problem.

The problem was in keras_applications.

There is two possible way to face this error message:

When the keras_applications library version is too old
When keras_applications are new but having trouble with TensorFlow's keras_preprocessing library

Anyway it occurred by .json file we can solve this problem by reinstalling Tensorflow and Keras-related things but I know that this works heavily stressful.

This is my personal recommendation for this kind of errors.

If you are sure that you installed Keras perfectly then just skipping its check process of Keras backend.

First, find your path of 'keras_applications' are installed (It might be in such 'C:\ProgramData\Anaconda3\Lib\site-packages' Or, just use 'pip show keras_applications')

And then, open (imagenet_utils.py) than edit it like this

from __future__ import absolute_import
from __future__ import division
from __future__ import print_function

import keras
import json
import warnings
import numpy as np
from . import get_keras_submodule
from . import set_keras_submodules


backend = set_keras_submodules('backend')
backed = 'backend'
keras_utils = get_keras_submodule('utils')

CLASS_INDEX = None
CLASS_INDEX_PATH = ('https://s3.amazonaws.com/deep-learning-models/'
                   'image-models/imagenet_class_index.json')

# Global tensor of imagenet mean for preprocessing symbolic inputs
_IMAGENET_MEAN = None

...

It's just editing check flag rightly (It should be checked by Keras backend API but because of version issue it impossible to check automatically sometimes).

This is possibly happening with the 'keras_preprocessing' library for the recent version (because some parts of 'keras_applications' are moved to 'keras_preprocessing) in this case you should edit the same parts on 'keras_preprocessing'

I know that this is not a perfect solution for the code, But it works okay temporarily.
(But I still highly recommend resetting your env..!)

You need to first `import keras` in order to use `keras_preprocessing`. For instance, you can do: about textgenrnn HOT 2 OPEN
