A issue in operate the code to start the demo of MD Net

[Huang9495]

First,I run the file named setup_mdnet.m in matlab ,then run the compile_matconvnet.m similarly in the matlab and at last when I run the file named demo_tracking.m,the issue is occuring.

Environment:

system:Ubuntu16.04,matlab:R2016b

Issues as fellows:

>> demo_tracking
Initialization...

Error in vl_simplenn (line 153)
      res(i+1).x = vl_nnconv(res(i).x, l.filters, l.biases, 'pad', l.pad, 'stride', l.stride) ;

Error in mdnet_features_convX (line 20)
    res = vl_simplenn(net, batch, [], [], ...

Error in mdnet_run (line 37)
    feat_conv = mdnet_features_convX(net_conv, img, pos_examples, opts);

Error in demo_tracking (line 22)
result = mdnet_run(conf.imgList, conf.gt(1,:), net);

What the issues is?This code I run in this environment is OK long time ago,but I operate it today ,the issues is occuring.

• compile matconvnet
• setup_mdnet

not the other way around
