Unable to run mask rcnn demo

[Deepanshu]

I successfully ran the squeeze_net and security_car demo on CPU and NCS2. But when I tried running openvino mask rcnn sample on ubuntu 16.04, it is showing the following error. Could someone help me with this ?

Following is the command that I tried running: 

$ python3 mo_tf.py --input_model /home/xt19i0024/Downloads/mask_rcnn_resnet101_atrous_coco_2018_01_28/frozen_inference_graph.pb

( I even checked the MO_FAQ question #38 but I was unable to figure it out )

Dear Raju, Deepanshu,

First of all, you're using an extremely old version of OpenVino. We are now on 2019R1.1. Please upgrade to the latest.

But upgrading will not solve your problem.  The mask rcnn demo doesn't work on MYRIAD right now.  The MYRIAD device literally runs out of memory. It's being addressed by the development team right now.

I'm very sorry about this. Thanks for your patience !

Dear Raju, Deepanshu,

Also regarding your model optimizer error, you're not using the correct mo_tf.py command for Tensorflow Object Detection API. Please follow this document:

Tensorflow Object Detection API MO Support

Thanks,

Shubha

Thanks for the quick response.

I think I had run the demo on the latest version itself. As you suggested upgrading the version to 2019R.1.1, so, I downloaded it again. I found out that the one I had previously downloaded and the one I downloaded recently are one and the same version/bits. Please correct me if I'm missing something. Here's the comparison:

xt19i0024@penna:~$ cksum ./Downloads/l_openvino_toolkit_p_2019.1.144.tgz ./openvino-toolkit/l_openvino_toolkit_p_2019.1.144.tgz

Dearest Deepanshu,

No  I think you're using the correct version of OpenVino. Are you saying that even after downloading the latest version of OpenVino and following the above instructions for Tensorflow Object Detection API, the mo command still fails for you ?

Thanks,

Shubha

[Deepanshu]

No, I could do the inference of mask_rcnn_demo on CPU on an image following the document that you shared. I just wanted to make sure that I've the latest version of OpenVino.

Thank you for addressing my query,

Deepanshu Raju
