My numpy version is 1.1.1. I just downloaded and installed. It is the same result. Also, when I use the list, I got similar error said list does not have the find command.
 
---> 14     fid=loadtxt(fname,comments='"',dtype='|S4',converters={cols:lambda s:int(s,16)},usecols=[cols])     15     16     #fid=loadtxt('ww36_5adcoutputsin45mhznotuner-0dbm_mux_adc_ddc_rmR.csv',comments='"',dtype='string',usecols=(0,))
C:\Python25\lib\site-packages\numpy\lib\io.pyc in loadtxt(fname, dtype, comments, delimiter, converters, skiprows, usecols, unpack)    337     for i, conv in (user_converters or {}).iteritems():    338         if usecols:--> 339             i = usecols.find(i)    340         converters[i] = conv    341
AttributeError: 'list' object has no attribute 'find'> c:\python25\lib\site-packages\numpy\lib\io.py(339)loadtxt()    338         if usecols:--> 339             i = usecols.find(i)    340         converters[i] = conv
 
Thanks
