<p dir="auto">When using tensorflow, I got hundred of DeprecationWarnings: This message exactly</p>
<blockquote>
<p dir="auto">/home/jerome/.local/lib/python3.5/site-packages/tensorflow/python/framework/tensor_util.py:560: DeprecationWarning: The binary mode of fromstring is deprecated, as it behaves surprisingly on unicode inputs. Use frombuffer instead<br>
return np.fromstring(tensor.tensor_content, dtype=dtype).reshape(shape)</p>
</blockquote>
<p dir="auto">EDIT : fixed replacing line 560 in tensor_util.py by :</p>
<p dir="auto"><code class="notranslate">return np.frombuffer(tensor.tensor_content, dtype=dtype).reshape(shape)</code></p>
<p dir="auto">Thanks for any kind of help :)</p>
<p dir="auto">I want to know if using estimator to train on multi gpus can share the mean and var of batchnorm.</p>
<p dir="auto">As the example in cifar, it cannot deal with the batchnorm sharing between different gpu</p>
