I'm using Boost.Python to wrap a C++ class that takes a std::vector<double> & as argument.. Using scitbx/include/scitbx/boost_python/container_conversions.h as suggested by the Boost.Python FAQ, I can correctly convert and use a Python sequence generated by numpy with
numpy.arange(10, dtype=numpy.float64 ) But when I change float64 to float32 I get an exception with message "No registered converter was able to produce a C++ rvalue of type double from this Python object of type numpy.float32" Disappointing but maybe understandable. So I change my C++ class to accept vector <float> and still get exception with "No registered converter was able to produce a C++ rvalue of type float from this Python object of type numpy.float32" ^^^^^ Strange, not the result I expected. Even stranger, if I change the python sequence to float64 while keeping the C++ with vector<float> it works fine; no exception. Any suggestions on how to get numpy.float32 handled? Also numpy.int64 converted to a double. _______________________________________________ Cplusplus-sig mailing list Cplusplus-sig@python.org http://mail.python.org/mailman/listinfo/cplusplus-sig
