Hello. I'm trying to convert ResNet50 caffemodels to dlc formats.

When I command

snpe-caffe-to-dlc --caffe_txt ResNet-50-deploy.prototxt --caffe_bin ResNet-50-model.caffemodel --dlc resnet50.dlc

it gives me messages like:

*** Error in `python': free(): invalid pointer: 0x0000000002656a70 ***

(... and so on)

and makes an dlc file, but I'm not sure it is converted correctly.

This is same with the result of alexnet tutorial.

python $SNPE_ROOT/models/alexnet/scripts/setup_alexnet.py -a ~/tmpdir -d 

Is there anybody who can help me? My environment setting is

- SNPE-1.19.2

- caffe (git revision 99bd99795)

- python 2.7

- Ubuntu 16.04

 

Thank you.
