[Numpy-discussion] fast way to convolve a 2d array with 1d filter

Hi,
 
I need to convolve a 1d filter with 8 coefficients with a 2d array of the shape (6,7). I can use convolve to perform the operation for each row. This will involve a for loop with a counter 6. I wonder there is 
an fast way to do this in numpy without using for loop. Does anyone know how to do it?
 
Thanks
 
Frank
