Model Optimizer cannot handle Caffe model

Jump to solution

Hi all,

 

I am trying to run `hello_reshape_ssd` example and for this I run the following commands:

```console

alias ov_model_downloader=$OPENVINO_DIR/deployment_tools/open_model_zoo/tools/downloader/downloader.py
alias ov_model_optimizer=$OPENVINO_DIR/deployment_tools/model_optimizer/mo.py

ov_model_downloader --name ssd300

ov_model_optimizer --framework caffe --input_model ./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.caffemodel

```

And for last command I get the following error:

```console

[ FRAMEWORK ERROR ] Exception message: [Errno 2] No such file or directory: '<Some Dir>/OpenVINO/inference-engine/samples/hello_reshape_ssd/./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.prototxt'

Possible reasons:
1. <Some Dir>/OpenVINO/inference-engine/samples/hello_reshape_ssd/./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.prototxt does not exist
2. <Some Dir>/OpenVINO/inference-engine/samples/hello_reshape_ssd/./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.prototxt does not have a valid structure, for example, it was downloaded as html
3. <Some Dir>/OpenVINO/inference-engine/samples/hello_reshape_ssd/./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.prototxt contains custom layers or attributes that are not supported
in Model Optimizer by default.

After you made sure that <Some Dir>/OpenVINO/inference-engine/samples/hello_reshape_ssd/./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.prototxt has a valid structure and still see this issue, then
you need to generate a python parser for caffe.proto that was used when the model
was created.
Run "python3 generate_caffe_pb2.py --input_proto ${PATH_TO_CAFFE}/src/caffe/proto/caffe.proto"
For more information please refer to Model Optimizer FAQ, question #1. (https://docs.openvinotoolkit.org/latest/openvino_docs_MO_DG_prepare_model_Model_Optimizer_FAQ.html?q...)


[ FRAMEWORK ERROR ] Model Optimizer is not able to parse <Some Dir>/OpenVINO/inference-engine/samples/hello_reshape_ssd/./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.prototxt

```

By some reason model optimizer cannot parse properly model that I downloaded from Open Model Zoo ...

 

Maybe I've missed some dependency ?

Seems like by some reason Model Optimizer detects this model as Tensorflow, because it tries to read .prototxt

I've checked ... issue fixed with Python 3.8 !!

Hello Denis Kotov,


Thank you for contacting us.


To convert the Caffee model to IR:

python3 mo_caffee.py --input_model /path/to/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.caffeemodel --input_proto /path/to/deploy.pototxt


Please visit Hello Reshape SSD C++ Sample page for more information.

I've checked it previously, but also I've read Model Optimizer documentation https://docs.openvinotoolkit.org/2021.2/openvino_docs_MO_DG_prepare_model_convert_model_Convert_Mode...

 

And there you can see there following line:

 

python3 mo.py --input_model <INPUT_MODEL>.caffemodel

 

 It seems like documentation is outdated ?

 

Also I've tested your command as it:

 

python3 $OPENVINO_DIR/deployment_tools/model_optimizer/mo_caffe.py --input_model ./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.caffemodel --input_proto ./public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/deploy.prototxt

 

And I still have got the same error ... (

Hello Denis Kotov,

 

What is the OpenVINO version that you use?

 

Try to put the full path to the input model and input proto. For instant:

python3 mo_caffee.py --input_model /opt/intel/openvino_2021.2.185/deployment_tools/open_model_zoo/tools/downloader/public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.caffemodel --input_proto /opt/intel/openvino_2021.2.185/deployment_tools/open_model_zoo/tools/downloader/public/ssd300/models/VGGNet/VOC0712Plus/deploy.prototxt/

 

Regards,

Zulkifli

I've tested with full path and the same issue ...

The version I am testing is `releases/2021/3`

And I am using downloaded models from Zoo that is located in current folder like `$PWD/public/ssd300/models/VGGNet/VOC0712Plus/SSD_300x300_ft/VGG_VOC0712Plus_SSD_300x300_ft_iter_160000.caffemodel`

Hello Denis Kotov,


Please try these steps. 

 

Install the dependencies.

Go to dependencies directory:

cd /opt/intel/openvino_2021/install_dependencies

Run the script:

sudo -E ./install_openvino_dependencies.sh

 

Set the environment variable:

source /opt/intel/openvino_2021/bin/setupvars.sh

 

Install the prerequisites:

Go to the Model Optimizer prerequisites directory:

cd /opt/intel/openvino_2021/deployment_tools/model_optimizer/install_prerequisites

Run the script:

sudo ./install_prerequisites.sh


Please inform us if you encounter any error while installing dependencies and prerequisites.


Regards,

Zulkifli

Nope ... still this issue:

[ ERROR ] Error while emitting attributes for layer relu1_1 (id = 5). It usually means that there is unsupported pattern around this node or unsupported combination of attributes.
