            ValueError: Error when checking target: expected dense_2 to have shape (1,) but got array with shape (14,)
            Asked 2019-Mar-09 at 07:16

            I am trying to train a classification model in a distributed way. I am using TensorflowOnSpark library developed by Yahoo. The example I am using github link

            I am using dataset other than mnist which is used in example mentioned in the github link. This dataset I am using is of dimensions as follows after preprocessing (260000,28047) and also the classes(labels) range from 0:13.

            ...

            As pointed out in comment by @Matias you are using wrong loss function

            Sparse cross entropy is used when your output is an integer like 0,1,2,3,..13. But your output is onehot encoded [0,0,...1,0].

            So use categorical cross entropy.

            QUESTION

            Error in the first step of running this example: TensorFlowOnSpark on a Spark Standalone cluster
            Asked 2018-May-22 at 15:04

            I have a problem with running this example TensorFlowOnSpark on a Spark Standalone cluster (Single Host):

            After executing mnist_data_setup.py file, it extracts the MNIST zip files correctly. But by calling extract_images(filename) functions, it faces an error. Please see the error in the following:

            ...

            ANSWER

            Answered 2018-Feb-20 at 22:38

            I think in the open, your provide a file type object instead of a string for the name variable.

            I do more digging:

            In images = numpy.array(mnist.extract_images(f)), f is a file object.

            But with tf.gfile.Open(filename, 'rb') as f, gzip.GzipFile(fileobj=f) as bytestream:, this treats the argument passed by images = numpy.array(mnist.extract_images(f)) as a filename.

            This behavior does not appear in the latest version: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/contrib/learn/python/learn/datasets/mnist.py
