QUESTION
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.
...
ANSWER
Answered 2019-Mar-09 at 07:16As 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
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 22:38I 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:
