Error when running using matconvnet1.0-beta23

[Naruto-Sasuke]

When I run demo.m, error happens like this:

`
错误使用 vl_argparse (line 52)
The name of the parameter number 1 is not a string.

出错 vl_nnrelu (line 34)
opts = vl_argparse(opts, varargin, 'nonrecursive') ;

出错 dagnn.ReLU/forwardAdvanced (line 29)
net.vars(out).value = vl_nnrelu(net.vars(in).value, [], ...

出错 dagnn.DagNN/eval (line 91)
obj.layers(l).block.forwardAdvanced(obj.layers(l)) ;

出错 demo (line 40)
net.eval({'data',img_prepared}) ;
`
How to solve the problem or what version should use?

Hi,
Please check

1. whether you have successfully compiled the matconvnet and vlfeat.
2. whether you have run setup.m script
   Please let me know how it goes. Good luck!

Hi,
I encountered the same problem and I am sure the matconvnet and vlfeat are both successfully compiled with running setup.m script. @zhanghang1989

Since the error occurs in net.eval command, anything related to vlfeat may be omitted.
