Error with Gradient boosted tree sample

[John Davis]

Hello

I'm trying to run this example code from a medium article.  The article links the source from the tensorflow.org site and the code between the three versions appears to be the same.  However, when I run the code, it will kill my jupyter notiebook kernel during the training.

Here is the error message:

The kernel appears to have died. It will restart automatically.

Here is the blog with the sample code I'm running.

https://medium.com/tensorflow/how-to-train-boosted-trees-models-in-tensorflow-ca8466a53127

Here is the section from the blog:

"Then training a Boosted Trees model involves the same process as above:"

 

This is the line which interrupts the kernel:

# The model will stop training once the specified number of trees is built, not 

# based on the number of steps.

est.train(train_input_fn, max_steps=100)

The log for the above cell shows this:

Any idea where to discuss this problem?
