Repository for reproducing issue: 3280: "Bug: MinibatchSource.GetNextMinibatch hangs (multiple serializers?"
- Clone this repository.
- Open the solution in visual studio 2017.
- Build and run the project CntkSerializerIssue
Image data is located in the images folder in the root of the repository. There are 4 directories, one for each channel:
- Channel1
- Channel2
- Channel3
- Channel4
Each directory contains the first 128 images of the "zero" class from the mnist data set. The original data set can be found here: http://yann.lecun.com/exdb/mnist So each channel contains the same set of gray level images. This does not matter for this case, since we are only trying to reproduce minibatch source/serializer issue.
The map and ctf files for training are located in the mapfiles folder in the root of the repository.
