How to make Keras use Tensorflow backend in Anaconda? : <p>I have install tensorflow-gpu in my Anaconda environment. They both work well. </p>

<p>Now I am trying to install Keras with Tensorflow backend. According to the <a href="https://keras.io/#installation" rel="noreferrer">instruction</a> I just run:</p>

<pre><code>pip install keras
</code></pre>

<p>But it doesn't install keras, then I tried:</p>

<pre><code>conda install -c conda-forge keras=2.0.2
</code></pre>

<p>Then I am now able import keras in python. But the problem is, it always use the Theano backend. I am trying to change this, but not knowing how to do it.</p>

<p>I also tried edit the file <strong>~/.keras</strong>, but actually default backend was tensorflow already.</p>

<p>Please help.. Thank you so much!</p>
