MxNet/example/rcnn/demo.py error

[hollyholly5]

demo.py error shows:
Traceback (most recent call last):
File "E:\2016prog\rcnnpython\demo.py", line 33, in

ValueError: Must specify all the arguments in args

How can I deal with it ?

Bind will issue this error when arguments are missing. Try listing arg_params.keys() and see if anything is missing. We uploaded a new demo for faster rcnn with a pretrained model. You are welcome to check that out.

@precedenceguo Thank you very much for your response.
I tried the pretrained model
python demo.py --prefix final --epoch 0 --image 000004.jpg --gpu 0
I got errors:
File "C:\Python27\lib\site-packages\mxnet-0.7.0-py2.7.egg\mxnet\base.py", line 77, in check_call
raise MXNetError(py_str(LIB.MXGetLastError()))
mxnet.base.MXNetError: [15:33:23] d:\chhong\mxnet\src\operator./convolution-inl.h:279: Check failed: (param.workspace) >= (required_size)
Minimum workspace size: 1135104000 Bytes
Given: 536870912 Bytes
[15:33:23] D:\chhong\mxnet\src\engine\naive_engine.cc:28: Engine shutdown

so I wonder this pretrained model requires what size of workspace. Sorry for the low level of my GPU: GTX 965

Please consider use cudnn to avoid this problem.

[marcociccone]

Hi have the same issue, I cannot use cudnn on my board. Could you elaborate on this problem? What is related to?

[ijkguo]

Please follow http://mxnet.io/api/python/symbol.html#mxnet.symbol.Convolution to set proper workspace for convolution.

[marcociccone]

Thank you for you help, now it’s working.

I got the same error ValueError: Must specify all the arguments in args,but i don't know how to deal with it.I use it in windows 10.I ran the command python demo.py --prefix final --epoch 0 --image myimage.jpg --gpu 0

[ijkguo]

It means some parameters are missing. Please check everything is there in arg_params and aux_params.

How and where can I set proper workspace for convolution?

[ijkguo]

Like this https://github.com/precedenceguo/mx-rcnn/blob/master/rcnn/symbol/symbol_vgg.py
