These modules should be all you need for Corr to work. Best, Hong On Fri, Mar 30, 2012 at 1:55 AM, Zhu Renjie <[email protected]> wrote: Hi, Hong Thank you for your information. I downloaded the construct package and copy it to the location. But another error message was founded. from corr import katcp_wrapper Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/corr/__init__.py", line 11, in <module> import cn_conf, katcp_wrapper, log_handlers, corr_functions, corr_wb, corr_nb, corr_ddc, scroll, katadc, iadc, termcolors, rx, sim, snap File "/usr/local/lib/python2.6/dist-packages/corr/rx.py", line 5, in <module> import spead ImportError: No module named spead These package seems not regular for the python, because when I use 'apt-get install', it can not find the constuct module and the spead module.

(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. The error message is: >>> from corr import katcp_wrapper Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python2.6/dist-packages/corr/__init__.py", line 11, in <module> import cn_conf, katcp_wrapper, log_handlers, corr_functions, corr_wb, corr_nb, corr_ddc, scroll, katadc, iadc, termcolors, rx, sim, snap File "/usr/local/lib/python2.6/dist-packages/corr/corr_functions.py", line 53, in <module> import corr, time, sys, numpy, os, logging, katcp, struct, construct ImportError: No module named construct How can I deal with this problem?
