Hello Authors

I have followed the exact steps mentioned in the guide to setup the working environment
I am working on Ubuntu 18.10 VM on virtual box within mac

Could you please help how to resolve this error below

AssertionError: AbstractConv2d Theano optimization failed: there is no implementation available supporting the requested options. 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?

Thanks I resolved the error by setting the flag as below
[global]
floatX = float32
device = cpu
optimizer = None
