Assertion Errors while importing Keras modules

I installed Keras using Pip and when I am trying to import modules from Keras, it gives me an assertion error on utils and init modules. 

---------------------------------------------------------------------------
AssertionError                            Traceback (most recent call last)

I found a similar question in SOF and checked 

 python -c "from keras import backend"

in cmd prompt and it gives me the following error. 

C:\ProgramData\Anaconda3\lib\site-packages\h5py\__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.

  File "C:\ProgramData\Anaconda3\lib\site- 
packages\keras\backend\__init__.py", line 36, in <module>
assert _backend in {'theano', 'tensorflow', 'cntk'}

AssertionError

Keras.json: 

{
"image_dim_ordering": "tf",
"backend": "mxnet",
"epsilon": 1e-07,
"floatx": "float32"
}

What should I be changing in these modules to avoid this error?

Thanks in Advance.

Based on your update with the contents of your keras.json file, it appears you have set the backend to "mxnet", but this is not a permitted backend of Keras.

Change this value to one of "tensorflow", "theano", or "cntk" and be sure you have that corresponding package also installed. Save the file and try again.
