Hi, Thank you for the suggestion. I was trying out an example code using PyArray_NewFromDescr*.* PFA of the code.I compiled the file using :python setup.py build_ext --inplace. When compiled I get the following error : fatal error : numpy/arrayobject.h :No such file or directory. I would be realy gratefull if you could do the edit in the file I sent in my first mail.
