ValueError: No JSON object could be decoded
dsu...@gmail.com
Hi all,
I have an issue with my keras setup on my new macbook pro. After installing (see setup below) first everything worked perfectly. I executed a test code using keras and it worked fine. After I edited keras.json to change the backend to theano it stopped working - even if I changed the backend back to tensorflow. It started to generate the error message below when importing Keras.
…Any help would be highly appreciated.
Cheers, Daniel
My system: Macbook Pro, Mac OS 10.12.1, 16 GB Ram, Radeon 460
My installation procedure (in this order)
1. Install anaconda2 4.2.0 (python 2.7) for Mac OS X
2. Conda install Theano
3. Conda install Tensorflow (CPU only)
4. Pip install keras
keras.json
{
"image_dim_ordering": "tf",
"epsilon": 1e-07,
"floatx": "float32",
"backend": “theano”
}
Code which produces error (first line already generates error)
