Reg: Error while training PDNN using maxout

[ellurunaresh]

Hi all,

I was running PDNN with dropout+maxout parameters. Found the error at DNN training.
Please help me out how to solve this issue.

*_Using gpu device 0: Tesla K40m
[2016-04-28 06:54:31.804045] > ... building the model
Traceback (most recent call last):
File "pdnn/cmds/run_DNN.py", line 85, in

layer.W.set_value(factor * np.asarray(string_2_array(nnet_dict[dict_a]), dtype=theano.config.floatX).reshape(mat_shape))
ValueError: total size of new array must be unchanged

Command used for training DNN is:

   $pythonCMD pdnn/cmds/run_DNN.py --train-data "$working_dir/train_tr95.pfile.*.gz,partition=2000m,random=true,stream=true" \
                                    --valid-data "$working_dir/train_cv05.pfile.*.gz,partition=600m,random=true,stream=true" \

                                    --ptr-file $working_dir/dnn.ptr --ptr-layer-number $numHidden \

                                    --activation "maxout:3" \
                                    --lrate "D:0.08:0.5:0.2,0.2:8" \
                                    --wdir $working_dir --kaldi-output-file $working_dir/dnn.nnet || exit 1;
