| X.flat returns an indexable 1-D iterator (mostly similar to an array |
| but always 1-d) --- only has .copy and .__array__ attributes of an array!!! |
| |
| .typecode() --> .dtype.char |
| |
| .iscontiguous() --> .flags['CONTIGUOUS'] or .flags.contiguous |
| |
| .byteswapped() -> .byteswap() |
| |
| .itemsize() -> .itemsize |
| |
| .toscalar() -> .item() |
| |
| If you used typecode characters: |
| |
| 'c' -> 'S1' or 'c' |
| 'b' -> 'B' |
| '1' -> 'b' |
| 's' -> 'h' |
| 'w' -> 'H' |
| 'u' -> 'I' |
| |
| |
| C -level |
| |
| some API calls that used to take PyObject * now take PyArrayObject * |
| (this should only cause warnings during compile and not actual problems). |
| PyArray_Take |
| |
| These commands now return a buffer that must be freed once it is used |
| using PyMemData_FREE(ptr); |
| |
| a->descr->zero --> PyArray_Zero(a) |
| a->descr->one --> PyArray_One(a) |
| |
| Numeric/arrayobject.h --> numpy/oldnumeric.h |
| |
| |
| # These will actually work and are defines for PyArray_BYTE, |
| # but you really should change it in your code |
| PyArray_CHAR --> PyArray_CHAR |
| (or PyArray_STRING which is more flexible) |
| PyArray_SBYTE --> PyArray_BYTE |
| |
| Any uses of character codes will need adjusting.... |
| use PyArray_XXXLTR where XXX is the name of the type. |
| |
| |
| If you used function pointers directly (why did you do that?), |
| the arguments have changed. Everything that was an int is now an intp. |
| Also, arrayobjects should be passed in at the end. |
| |
| a->descr->cast[i](fromdata, fromstep, todata, tostep, n) |
| a->descr->cast[i](fromdata, todata, n, PyArrayObject *in, PyArrayObject *out) |
| anything but single-stepping is not supported by this function |
| use the PyArray_CastXXXX functions. |
