Keras: failed to switch the backend even after changing keras.json

[wenouyang]

Hi, I changed thekeras.jsonto enforce it use Theano as backend, shown as following

bash-4.1$ cat ~/.keras/keras.json
{"floatx": "float32", "epsilon": 1e-07, "backend": "theano","image_dim_ordering": "th"}

However, when running the program, it still show that Tensorflow is backend. How to solve this issue? Thanks.

I'm having the same problem. I updated the names in my ~/.keras/keras.json file, but it made no difference. If I set the KERAS_BACKEND environment variable to theano, keras loads Theano, but it appears to be ignoring the keras.json file.

Did you install Keras using conda-forge? It seems that the issue is the file keras_activate.sh that comes with the forge package, the KERAS_BACKEND is hardcoded to TensorFlow for mac:

#!/bin/bash if [ "$(uname)" == "Darwin" ] then # for Mac OSX export KERAS_BACKEND=tensorflow elif [ "$(uname)" == "Linux" ] then # for Linux export KERAS_BACKEND=theano fi

Yes. Thanks!
