Did you exclude both \"conv_dnn\" and \"conv_gemm\" from the optimizer? If on GPU, is cuDNN available and does the GPU support it? If on CPU, do you have a BLAS library installed Theano can link against?**\r\n\r\nI've looked at similar issues on Theano/Keras github issues page. \r\nAlmost all the solutions pointed towards updating Theano & Keras. \r\nI've tried updating both of them, and that didn't resolve the issue. \r\n\r\nIs the issue in how we give the images to the training function(model.fit)?\r\nIn what format should the 2D grey scale images be given as the training set?\r\nCould someone please help me out in fixing this.\r\n\r\nPlease find the link to the code & error [here](https://github.com/Vivek-B/Kaggle/blob/master/Digit%20Recognition/Conv-2D%20--%20Keras.ipynb)"}}
