Try reduce batch size from 128 to 100. |
I have try to reduce batch size to 50, but it doesn't work |
Try to fix the value "gpu_memory" of your .pbtxt file to "2G" or "2.5G" |
thanks , that's OK |
thanks to you in advanved File "/home/tbq/Downloads/deepnet-master/deepnet/softmax_layer.py", line 65, in GetLoss and the RAM is 1G and gpu memory is 256M in my computer ,CUDA5.5 when i try the dbm and rbm ,it is also comes to the problem |
sorry,english is not mother tongue. in addition,gcc:4.6.3 |
In my case, I decreased |
thank you all , ruducing the gpu_mem really helps , and the code strat to work , but at the end of trainning the first layer , the bug happens again , is the gpu_mem still too large? Thank you all a lot if anyone can help me |
hi nitish srivastava

I have problems when running multimodal_dbm example, like this:

cudamat.cudamat.CUDAMatException: CUBLAS error.
and the RAM is 8G and gpu memory is 3G in my computer ,CUDA6.0
I follow your INSTALL, but always happen this
could tell how to resolve this ? It's a bug?
thx
