@portgasray
Did you download and convert a trained model to produce an IR, refer to the segmentaton download and convert section in this guide.

@RachelRen05 Hi, I need help. I can not exec python3 ./downloader.py --name mobilenet-ssd in Object Detection, it needs to connect to the host docs.google.com, any suggestion?

@portgasray
Hi, we have never encountered this problem, can you provide a detailed error log?

@RachelRen05
Sure, first. the guide you provided I could not use it (404 page).
then I found the new guide according to the URL string BINARY_VERSION_README.

I perform the 5. Running the Demo under the guide of BINARY_VERSION_README.

It is also a 404 page when I clicked download Object Detection model in the second step of Preparation.(See the following)

I tracked the page where it jumped to and found the OBJECT_DETECTION instead.
404

Finally, My issue happened here, when I perform the step mobilenet-ssd, the second command python3 ./downloader.py --name mobilenet-ssd occored the following error:

In my opinion, It caused by the network connection.

according to the error info, I performed an experiment that I combined the url.

First, I opened on the web browse and it succeed.

then I used the wget on the server where the error happened
