How to solve this issue

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,gpuArray(im),[],[],'CuDNN',false, 'Mode', 'test');

Error in extract_features (line 48)
feature_map(ind:ind+num_blocks-1) = feat.getFeature(img_samples{img_sample_ind}, feat.fparams, gparams);

Error in tracker (line 275)
xl = extract_features(im, sample_pos, currentScaleFactor, features, global_fparams, feature_extract_info);

Error in testing_CFWCR (line 98)
results = tracker(params);

Error in demo_CFWCR (line 13)
results = testing_CFWCR(seq);
