Hi Renjie, I think you just need to install the python module "construct" by doing something like "yum install python-construct", or as this ( http://construct.wikispaces.com/install) says, just download the zip file and extract it to "/usr/local/lib/python2.6/dist-packages/". (Are you using Ubuntu? The webpage says site-packages but I think it should be dist-packages in your case).
Hope it works, Hong On Thu, Mar 29, 2012 at 11:57 PM, Zhu Renjie <[email protected]> wrote: > Dear all, > > I try the basic ROACH board interaction. > When I instantiate an FpgaClient object with 'from corr import > katcp_wrapper' with python.
