[Numpy-discussion] unpacking bytes directly in numpy

To convert some bytes to e.g. a 32-bit int, I can do

bytes = f.read(4)
i = struct.unpack('>i', bytes)[0]

and the convert it to np.int32 with

i = np.int32(i)

However, is there a more direct way of directly transforming bytes  
into a np.int32 type without the intermediate 'struct.unpack' step?

Thanks for any help,
