I am running tensorflow/models/image/mnist/convolutional.py. I get:

Can you do the following:

Build //tensorflow/models/mnist:convolutional via:

bazel build -c dbg //tensorflow/models/mnist:convolutional

And run with gdb:

(assuming your python is in /usr/bin/python2.7)
gdb --args /usr/bin/python2.7 bazel-bin/tensorflow/models/mnist/convolutional

(press "r" to run it)

wait until it crashes; and type "bt" for backtrace

paste the resulting output here.

I have pushed a fix for this assertion to our internal tensorflow code repository. It will be available on github with the next push.

I believe this is fixed as of 9c3043f, will be in our next binary release
