Model download timeout :download.01.org

julia76

I have depthai_demo running happily with the inbuilt model but I get repeated timeout error when I try to down load a different model. With my browser I can access www.01.org but I get a timeout from download.01.org I tried abcdef.01.org and I get not found. I am located in England and wonder if there is some form of export restriction?

The included dump is from python 3.8 with pycharm, ubuntu 20.3. I get similar errors when I tried windows 10. I have tried different models.

Sorry about the trouble here. Are you able to reach http://69.164.214.171:8083 from your browser?

We can also provide these models for download from Google drive if that is helpful.

Speaking of which, this set of examples has the models included in the repo, if you'd like to try those in the meantime:
https://github.com/luxonis/depthai-experiments/tree/master/gen2_examples

Thanks and sorry for the trouble.

julia76

Yes I can access http://69.164.214.171:8083. I can make and download a blob file for face-detection-retail-0004.
I have played around a bit and I can get other models to download but not any of those which download from downloads.01.org. The intel docs seem to say the model has been replaced by a later version. Is it only me?

Brandon

Oh interesting. We will investigate and see about hosting these directly instead.

julia76

How do I make depthai_demo use the downloaded blob file?
I tried placing face-detection-retail-0004.blob in the resources/nn/face-detection-retail-0004 folder with the model.yml file bit it still tried to download from 01.org. It there a way to download the xml and bin files?

The models I can download are:-
yolo-v3, OK
deeplabv3p_person, OK
mobileNetV2-PoseEstimation
vehicle-license-plate-detection-barrier-0106,
tiny-yolo-v3, OK
mobilenet-ssd, OK

I think the problem is that downloads.01.org does not use the latest download protocol and recent chances to outlaw the use of the older insecure protocols. I don't know whether the restriction is enforced locally in my computer or globally in the web infrastructure. If it were just my laptop there might be a way to reactivate the old protocols. (I tried and failed but it is not my area of expertise)

I found when testing with mobilenet-ssd that the scripts have multiple places that need to be flushed to force a new download.

julia76 Sorry about the delay. Yes, I think we recently wrote a tutorial on how to do this, checking with the team and will circle back.

There are certain naming conventions for the blobs copied into resources/nn/. It should match [MODEL_NAME].blob.shXcmxXNCE1. Where X is filled in with the number of SHAVEs and CMX used. For example, you could move it to resources/nn/face-detection-retail-0004.blob.sh14cmx14NCE1. Let me know if that works!

Best,
Philip

Thanks Philip. Getting the correct suffix got it working.

Correction I incorrectly stated that vehicle-license-plate-detection-barrier-0106.xml can be downloaded

julia76

Hunting around I found these later copy of the models:-
https://storage.openvinotoolkit.org/repositories/open_model_zoo/2021.2/models_bin/3
Is in possible to use these?

We only formally support up to 2021.1, but we should be adding support for 2021.2 soon. Until then you can still try to use those models since they may be backwards compatible.

Best,
Philip

I have just got something working using openVINO_2021.2

I used apt to install intel-openvino-runtime-ubuntu20-2021.2.200 & intel-openvino-dev-ubuntu20-2021.2.200
If I try installing anything older than openVINO_2021.1 the installation scripts fall over since they don't recognise the latest version of Ubuntu. I can install openVINO_2021.1 but that falls over as it tries to download from downloads.01.org (which is my original problem)

The demo script './demo_benchmark_app.sh -d MYRIAD' runs on my OAk1 as do the other demos in the openVINO distribution.

I'm having the same issue with downloading:
requests.exceptions.HTTPError: 504 Server Error: Gateway Time-out for url: https://download.01.org/opencv/2020/openvinotoolkit/2020.1/open_model_zoo/models_bin/1/face-detection-retail-0004/FP16/face-detection-retail-0004.xml

smd58tex

Aaaand I should follow up by saying it's working now. Perhaps the host is just unreliable?

Same issue, do I need to resort to using a manually-created blob file? Unlike julia76, I'm not able to access http://69.164.214.171:8083/ from the browser. Removing the port from the url (http://69.164.214.171 ), I am able to load from browser.

Noticing that luxonis.com has ssl, I changed the URL used in model_compiler.py to https and added luxonis ssl cert to my python environment's cacert.pem file.

This produced a different error:

Still not sure how to remedy. Any insight would be helpful.

dnavs Update: Success! I'm attempting this from within our organization's network. I tried running the depthai_demo.py while connected to wifi outside my network (using the original http://... URL) and things downloaded as expected. I suspect my company is blocking non-encrypted traffic.

Thanks @dnavs ! That makes way more sense now. I should have thought of that. And thanks for circling back with the resolution. (And sorry about the delay, European Brexit/pandemic logistics issues have been consuming so many hours.)
