                I’m not sure what you’re trying to do. 
You want to apply a convolution with a kernel size of 7 to a 1d vector of size 13, is that correct ? 
In that case your input should be a tensor with 1 channel containing a 1D vector of size 13. 
So your input size should be [7,  1,  13] (batch_size, channels,…
