Errors while using pre-trained ssd_inception_v3 model in demo.py

[arisha07]

Hello @zhreshold, I have been trying to run the demo.py using the pre-trained ssd_inception_v3 by using the following command. Also I extracted the pre-trained files from ssd_inceptionv3_512_voc0712trainval.zip to the model folder. command-- python demo.py --cpu --network inceptionv3 --images ./data/demo/dog.jpg errors-- mxnet.base.MXNetError: Failed loading Op _minus0 of type elemwise_sub: [16:58:33] src/core/op.cc:55: Check failed: op != nullptr Operator elemwise_sub is not registered

Am I missing something here ?

I got the relative issue. I'd like to train with my own dataset with inceptionv3. Did you download the model here?

Is this model for trainning or for inferrence?

[yanhn]

I also downloaded the model, and my scripts looks like this, and it worked. python demo.py --gpu 0 --network inceptionv3 --data-shape 512 --epoch 215 maybe you miss --data-shape 512 and --epoch 215

And I got the answer to my question. The model is for inferrence, so I need to find a model for tranning.

@arisha07 You might be using a very old mxnet version

@zhreshold I will try with the new version again...Thanks for the response.

[arisha07]

@zhreshold I re-installed mxnet and now I have 1.0.0 version. I am still facing issues- mxnet.base.MXNetError: [10:44:04] src/io/local_filesys.cc:166: Check failed: allow_null LocalFileSystem: fail to open "/home/arisha/mxnet-ssd/model/ssd_mobilenet_512-0000.params"

I am not sure what I am missing here.
