Error using vl_argparse

[xiaoqiao728295]

Dear author,

i have installed matconvnet successfully. When running Demo.m, i got some errors. Just showed below:
Error using vl_argparse (line 91)
Expected either a param-value pair or a structure.

Error in cnn_train_dag (line 26)
[opts, varargin] = vl_argparse(opts, varargin);

Error in CREST_tracking (line 117)
info = cnn_train_dag(net_online, imdb, input,getBatchWrapper(opts), ...

Error in Demo (line 32)
result=CREST_tracking(opts,varargin,config,display);

I think that there is something wrong with your input variable values in the function "cnn_train_dag", or "getBatchWrapper", but i can't find the solution about that error. Has anyone else had the same problem when running Demo.m?

Thank you for your time, i am looking forward to your reply.

do you solve this problem? i think this code released by the author has some typo!

[YingjieYin]

i can't run the code successfully too.

[YingjieYin]

I give the following changes , and then run the code sueessfully.

File: CREST_tracking.m :

% training options (SGD)
opts.train = struct('gpus',1) ;%%this is the changed part
[opts, varargin] = vl_argparse(opts, varargin) ;

File: /matconvnet/examples/+solver/adam.m :

if isequal(state, 0)||isempty(state) % start off with state = 0 so as to get default state
state = struct('m', 0, 'v', 0, 't', 0);
end

do you have other solution

[caoyuan-1]

you can use the /+solver/adam.m in author codes,not the file in matconvnet download from HOME

@xiaoqiao728295 hello,I met the same problem.I have tried your solution but still can't fix it .Do you have deal with the problem?

I found the problem is that in the file CREST_tracking.m, line 233, there is no function getBatch included. @ybsong00 please check your code. Thank you very much for your great project.

I solved the problem. Actually, there are 2 cnn_train_dag.m files. One is in the CREST folder and the other one is in CREST-Release-master/matconvnet/examples/. Make sure that you are using the first one, not the second.
