python - AssertionError when attempting to import keras related to backend -


so, when attempting import keras, following assertionerror appears:

    /home/m7nz/anaconda3/envs/ninja-01/lib/python3.6/site-packages/keras/backend/__init__.py in <module>()      32     assert isinstance(_epsilon, float)      33     _backend = _config.get('backend', _backend) ---> 34     assert _backend in {'theano', 'tensorflow'}      35     _image_data_format = _config.get('image_data_format',      36                                      image_data_format())  assertionerror:

keras.json follows:

{ "floatx": "float32", "epsilon": 1e-07, "backend": "theanos", "image_data_format": "channels_last"

i've tried deleting reference tensorflow in init.py file, error remains.

it's on linux machine, running ubuntu 16. using anaconda3. it's in anaconda environment.

thank help.

change

"backend": "theanos",

to 

"backend": "theano",

that typo in json file :-)
