difference between macro USE_METAL, CAFFE2_USE_MPSCNN & CAFFE2_MOBILE #1638

Open xhsoldier opened 6 years ago

xhsoldier commented 6 years ago

For iOS system, do I need to enable all these macros? USE_METAL, CAFFE2_USE_MPSCNN CAFFE2_MOBILE

pietern commented 6 years ago

@bwasti Do you know this?

jerryzh168 commented 6 years ago

USE_METAL is deprecated. If you just use CPU, you can enable CAFFE2_MOBILE. If you want to use iOS GPU, you should enable both CAFFE2_MOBILE and CAFFE2_USE_MPSCNN.

i enable the both CAFFE2_MOBILE and CAFFE2_USE_MPSCNN. then compile with a error: caffe2/caffe2/mobile/contrib/ios/mpscnn/mpscnn.mm:24:10: fatal error: 'caffe2/mobile/fb/aloha/headers.h' file not found

include "caffe2/mobile/fb/aloha/headers.h"

@jerryzh168 I couldn't get the master branch compile with flags CAFFE2_USE_MPSCNN and CAFFE2_MOBILE. It only seems to accept USE_METAL flag though.

There are problems with header files. We're looking into it, will give an update when it is resolved.

Should be fixed in #1690 now - feel free to reopen if it does not work.

the libcaffe2.a was succussfully built. But when I use the lib, I got a error:
