Hi Edward, This error message is issued on entry into C when libnumarray attempts to get a pointer to the data buffer of an array using the buffer API and fails for some reason. Is there anything fancy (memory mapping, Python array object, etc.) about the buffer your array is based on? Can you reduce the error to a short segment of code so we can reproduce the problem? What does arrout.info() report? Regards, Todd On Fri, 2003-12-26 at 11:49, Edward C. Jones wrote:
