ValueError when runing train.py

[rsindper]

Hi there, I got an ValueError when runing the training command instructed in the tutorial,

Traceback (most recent call last):
File "train.py", line 196, in

I put the data under fold mnist_dataset/data_train.bin

Hi, I note that you use python 3.7, while our code is based on python 2.7. Could you please set up an e.g., virtualenv of python 2.7 and have a try? Sorry for the inconvenience.

You can simply install pip install virtualenv and run virtualenv --system-site-packages -p python2.7 env_py27, without installing anaconda. Besides the TensorFlow version we used is 1.9.0, different versions of TF may deprecate or change some APIs.
