Error using imresize about faster_rcnn HOT 4 CLOSED

It seems that your Matlab does not have the over overloading of imresize for gpuArray.

A simple modification is that, you can commente out
Line 52, 76 in script_faster_rcnn_demo.m
"im = gpuArray(im);"

Thus the operation of image resize will use cpu instead of gpu. A side effect is slower testing speed.

@ShaoqingRen hi, i also commented Line 28,29, then succeeded. Thanks!

@ShaoqingRen Hi, I also encounter this problem this morning. The reason I wrote this comment is that I found even after I comment line 52,76 and line 28, 29 (as suggest by @xmubingo), there is still an error in the num.m. Actually the error occurs on line 34

nms_gpu_mex(single(boxes)', double(overlap));

and line 43

nms_mex(double(boxes), double(overlap));

both say the function is undefined.

Therefore I thought if I miss some installation steps? I'm using matlab 2013a and I'm sure to execute make matcaffe with no errors (caffe in this repository).

And currently my solution is using this file https://github.com/rbgirshick/fast-rcnn/blob/master/matlab/nms.m to temporarily replace nms.m. (Plus adding a peudo parameter use_gpu) Any suggestions?

Thank you for your time!

@oh233

You have this problem because matlab can not find the mex file that contains the function.
so the file in "functions/nms/nms_mex.cpp" and "functions/nms/nms_gpu_mex.cu" need to be compiled!

you can compile them by running the script called: "faster_rcnn_build.m" in the home directory as mentioned in the README.md

See Snapshot
Undefined function 'nms_mex' for input arguments of type 'double'.
