New issue 2874: numpy.frombuffer(ffi.buffer(x)) fails with the official numpy module. https://bitbucket.org/pypy/pypy/issues/2874/numpyfrombuffer-ffibuffer-x-fails-with-the
HexDecimal: This is valid CPython code, it also works on PyPy with the pypy/numpy fork: ```python import cffi, numpy ffi = cffi.FFI() c_array = ffi.new('int[4]') buf = ffi.buffer(c_array) np_array = numpy.frombuffer(buf, numpy.intc) print(np_array) ``` But when run on PyPy with the official numpy module you'll get this error: ``` Traceback (most recent call last): File "test.py", line 5, in <module> np_array = numpy.frombuffer(buf, numpy.intc) AttributeError: '_cffi_backend.buffer' object has no attribute '__buffer__' ``` I can work around the error on PyPy3 by wrapping `buf` in a `memoryview` but that breaks Python2. _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
