Enhancement for Google Colab #18

Open atotev opened 6 years ago

atotev commented 6 years ago

Hi,

I am new to Deep Learning, TF, and tools. I am trying out the examples using Google Colab. One thing I am noticing with the Ch. 3 examples is that I am getting a "placeholder not set" kind of error after I have run the notebook once:

InvalidArgumentError: You must feed a value for placeholder tensor

One workaround is to select Runtime > Restart Runtime... from the menu which is a bit cumbersome and time consuming if you want to experiment with the example and run it many times.

A better approach would be to call tf.reset_default_graph() in the beginning of the program or right before the placeholders are created. I think this would make things easier for people relying on the Google Colab or similar environments.

Thank you, Andrey

Another issue that seems to be in the way of Google Colab is matplotlib being configured to use LaTeX. Removing this initialization piece fixes the issue:

from matplotlib import rc
rc('text', usetex=True)

A great help if you want to install and use deepchem in Google Colab: https://github.com/christianmerkwirth/colabs/blob/master/graph_convolutional_networks_for_tox21_on_colab.ipynb
