Hi, I just downloaded the code tonight. I was able to run 0_tf_hello_world.ipynb and 1_linear_regression_model.ipynb without problem, except some warning messages.
But I got error running 2_mnist.ipynb, starting from Step 2.6. The error messages are "ValueError: Only call sparse_softmax_cross_entropy_with_logits with named arguments (labels=..., logits=..., ...)".
I am using TensorFlow version 1.1, Python 3.5 and Window 10.
