c++ - cuda, pycuda -- how to write complex numbers -- errors:class "cuComplex" has no member "i" - i have difficulties utilize complex numbers in cuda,pycuda. i have in c: #include <complex> typedef std::complex<double> cmplx; .... cmplx j(0.,1.); also,in same code: #include <boost/python.hpp> #include <boost/array.hpp> ... typedef std::vector< boost::array<std::complex<double>,3 > > complexfieldtype; typedef std::vector< boost::array<double,3> > realfieldtype; ... __global__ void compute(realfieldtype const & rs,complexfieldtype const & m,..) ... how can convert utilize pycuda? tried sth (according book 'cuda example'): struct cucomplex { float real; float imag; cucomplex(float a,float b): real(a),imag(b){} cucomplex operator *(const cucomplex& a) { homecoming cucomplex(real*a.real -imag*a.imag ,imag*a.real +real*a.imag); } cucomplex operat...

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
