my-detection.py "ssd_mobilenet_v2_coco.uff' was not found." error.

Hi, I've been working with the amazing jetson inference projects for several weeks now. And it was working great until I suddenly started to receive an error regarding the pretrained model file. I can confirm that the ssd_mobilenet_v2_coco.uff file exists under networks directory. I'm on Jetson Nano, with a compatible Logitech USB Webcam.

The exact console output is as follows:

jetson.inference.init.py jetson.inference -- initializing Python 3.6 bindings... jetson.inference -- registering module types... jetson.inference -- done registering module types jetson.inference -- done Python 3.6 binding initialization jetson.utils.init.py jetson.utils -- initializing Python 3.6 bindings... jetson.utils -- registering module functions... jetson.utils -- done registering module functions jetson.utils -- registering module types... jetson.utils -- done registering module types jetson.utils -- done Python 3.6 binding initialization jetson.inference -- PyTensorNet_New() jetson.inference -- PyDetectNet_Init() jetson.inference -- detectNet loading build-in network 'ssd-mobilenet-v2'

error: model file 'networks/SSD-Mobilenet-v2/ssd_mobilenet_v2_coco.uff' was not found. if loading a built-in model, maybe it wasn't downloaded before.

    Run the Model Downloader tool again and select it for download:

       $ cd <jetson-inference>/tools
       $ ./download-models.sh

detectNet -- failed to initialize. jetson.inference -- detectNet failed to load built-in network 'ssd-mobilenet-v2' PyTensorNet_Dealloc() Traceback (most recent call last): File "detect.py", line 4, in net = jetson.inference.detectNet('ssd-mobilenet-v2', threshold=0.5) Exception: jetson.inference -- detectNet failed to load network

I cannot seem to find a solution and hope to hear from you soon.

Thank you very much!

I am getting the same error.. Have you managed to solve it @canozcivelek ?

Hey! You can download it in here. https://github.com/dusty-nv/jetson-inference/releases choose that which you need, and unzip it under data/networks.
