Issue 1:
The first tf.contrib.learn sample at

https://www.tensorflow.org/get_started/get_started

fails to run.

The code is right under

"Basic usage

Notice how much simpler the linear regression program becomes with tf.contrib.learn:"

Output:

WARNING:tensorflow:Using temporary folder as model directory: C:\Users\John\AppData\Local\Temp\tmpahtnt89p

WARNING:tensorflow:Rank of input Tensor (1) should be the same as output_rank (2) for column. Will attempt to expand dims. It is highly recommended that you resize your input, as this behavior may change.

WARNING:tensorflow:From C:\Users\John\AppData\Local\Programs\Python\Python35\lib\site-packages\tensorflow\contrib\learn\python\learn\estimators\head.py:521: scalar_summary (from tensorflow.python.ops.logging_ops) is deprecated and will be removed after 2016-11-30.

Instructions for updating:

Please switch to tf.summary.scalar. Note that tf.summary.scalar uses the node name instead of the tag. This means that TensorFlow will automatically de-duplicate summary names based on the scope they are created in. Also, passing a tensor or list of tags to a scalar summary op is no longer supported.

If installed from binary pip package, provide:

A link to the pip package you installed:

pip install --upgrade https://storage.googleapis.com/tensorflow/windows/cpu/tensorflow-1.0.0rc2-cp35-cp35m-win_amd64.whl (to fix the BestSplits" error)

Issue 2:
Please go to Stack Overflow for help and support:

https://stackoverflow.com/questions/tagged/tensorflow

If you open a GitHub issue, here is our policy:

It must be a bug, a feature request, or a significant problem with documentation (for small docs fixes please send a PR instead).

The form below must be filled out.

It shouldn't be a TensorBoard issue. Those go here.

Here's why we have that policy: TensorFlow developers respond to issues. We want to focus on work that benefits the whole community, e.g., fixing bugs and adding features. Support only helps individuals. GitHub also notifies thousands of people when issues are filed. We want them to see you communicating an interesting problem, rather than being redirected to Stack Overflow.
