Models: Isuue with models/tutorials/image/mnist

[abdasgupta]

The MNIST example seems to have problem in running with Tensorflow:
Hi, I am completely new in TensorFlow. I just built TensorFlow and tried to run models/tutorials/image/imagenet/classify_image.py and it ran. But when I tried MNIST, I found the following error:

abhishek@phoebusdev:~/Documents/Works/models/tutorials/image/mnist$ python convolutional.py --self-test

ValueError: Only call sparse_softmax_cross_entropy_with_logits with named arguments (labels=..., logits=..., ...)

Am I doing anything wrong?

[aselle]

Is this related to your recent changes @martinwicke

[sugartom]

Exactly same issue...

[httr01]

getting same problem

[fishtown]

face the same situation, may anyone help to figure out which commit should I revert?

[martinwicke]

Sorry about that. I think I fixed it, please try it.

[dyoung418]

I'm getting the same problem today (using up-to-date source I pulled and compiled tonight).

[sugartom]

I am seeing the same error message when running python /usr/local/lib/python2.7/dist-packages/tensorflow/models/image/mnist/convolutional.py, but mnist is running normally if I run code under this repo python models/tutorials/image/mnist/convolution.py. And I found that the reason is you guys have changed interface under this repo but not the one under tensorflow/tensorflow?:

/usr/local/lib/python2.7/dist-packages/tensorflow/models/image/mnist/convolutional.py
loss = tf.reduce_mean(tf.nn.sparse_softmax_cross_entropy_with_logits(logits, train_labels_node))

this repo:
loss = tf.reduce_mean(tf.nn.sparse_softmax_cross_entropy_with_logits(labels=train_labels_node, logits=logits))

[martinwicke]

We're preparing this repo to be compatible to TensorFlow at head, which
will become TensorFlow 1.0. At that point they should be back in sync. This
will cause some disruption in the meantime. I apologize. You should be able
to use the nightly builds.

i meet the same issue on TF 1.0, when training Faster RCNN

[snsie]

I have also hit this error while training corgi's Faster RCNN.

Error log is listed below.

For those meet the same issue in TensorFlow r1.0, please reference this fix to change the code.

@rivendell1984 Thanks! I solved my problem of training faster RCNN with TF 1.0 following your suggestion.

[psuff]

cross_entropy = tf.nn.sparse_softmax_cross_entropy_with_logits(
logits=logits, labels=labels, name='xentropy')

just write logits=logits and labels=labels and it works

[bsed]

loss = tf.reduce_mean(tf.nn.sparse_softmax_cross_entropy_with_logits(logits=output, labels=tf.cast(tf.reshape(X, [-1]), dtype=tf.int32)))
