Error when I run demo_ECO_gpu.m？

[trikim]

I have succeed to run the demo_ECO.m and demo_ECO_HC.m file. However, I have encountered these errors. Error using vl_nnconv An input is not a numeric array (or GPU support not compiled).

Error in vl_simplenn (line 300) res(i+1).x = vl_nnconv(res(i).x, l.weights{1}, l.weights{2}, ...

Error in get_cnn_layers (line 23) cnn_feat = vl_simplenn(fparams.net, im,[],[],'CuDNN',true, 'Mode', 'test');

Error in extract_features (line 59) feature_map(ind:ind+num_blocks-1) = feat.getFeature(img_samples{img_sample_ind}, feat.fparams, gparams);

Error in tracker (line 347) xl = extract_features(im, sample_pos, currentScaleFactor, features, global_fparams, feature_extract_info);

Error in testing_ECO_gpu (line 129) results = tracker(params);

Error in demo_ECO_gpu (line 13) results = testing_ECO_gpu(seq);

Could you help to fix these problems?

i met the same problems

the same error

I was able to fix this error by switching the order in which the matconvnet directories are added to the path in setup_path.m (lines 20-22), as:

addpath([pathstr '/external_libs/matconvnet/matlab']);
addpath([pathstr '/external_libs/matconvnet/matlab/simplenn']);
addpath([pathstr '/external_libs/matconvnet/matlab/mex/']);

Hmm interesting. Note that I have only verified that it works with the older version of matconvnet, i.e. the one you get by running 'git submodule update'.

what GPU version did you use?8.0 or 7.5? Beacuse I met the same error when I use GPU 8.1 even if the matconvnet directories are added to the path!!!! Any else method???

Have you compiled matconvnet properly?

I have compile matconvnet-GPU already(win10+vs2017+cuda9.2+cudnn7.6), but the demo_ECO_gpu.m goes error by "An input is not a numeric array". I try @vivinousi solution method, is work, program run perfect. nice try!!!

Thank you for the solution. It is fixed in the code now.
