Deep Learning - Data no longer exists on the device

16 views (last 30 days)
I got the following error when trying to implement a deep learning NN in MATLAB.
Error using trainNetwork (line 154) The data no longer exists on the device.
Caused by:
Error using nnet.internal.cnngpu.batchNormalizationForwardTrain
The data no longer exists on the device.
Any suggestions?

This would happen if you are resetting the device or switching device using reset or gpuDevice. Perhaps you have a custom layer which is innocuously calling gpuDevice(1); this is resetting the device and invalidating all GPU data.

thank you! my network is running out of GPU memory!

In my case, I had similar problems, despite of the fact that I have a gtx1080Ti.
As Joss said, reducing the MiniBatchSize solved my problem. It's all about the training options.
