Hugging Face Model Not Supported
I have a question about the ARC "Hugging Face" Robot Skill.
I set up the API as instructed. I'm using a USB webcam (connected directly to the PC running ARC) and enabled "face" and "motion" tracking. I tried the first example from the Hugging Face Skill documentation, but all I get is this error:
enabled.","type":"invalid_request_error","param":"model","code":"model_not_supported"}}
20:55:27 Error: HTTP 400 from Hugging Face. {"error":{"message":"The requested model 'Qwen/Qwen2.5-VL-7B-Instruct' is not supported by any provider you have enabled.","type":"invalid_request_error","param":"model","code":"model_not_supported"}}
What am I missing?

Camera Device

Use PC or robot cameras for vision tracking: color, QR, glyph, face, object, motion; record video/data, control servos and movement, run scripts
Hugging Face
by Hugging Face Inc
Connects your robot camera to Hugging Face AI models for vision chat, object tracking, classification, captioning, and autonomous movement.
Requires ARC
v3

Absolutely - let’s break this into three clean steps and keep each test isolated so we can find the exact failure point.
1) Known-good ARC camera + Hugging Face test setup
This is the best first test because it removes extra variables.
Goal
Confirm that:
Steps
A. Create a new project
B. Add only the Camera Device skill
C. Configure the webcam
You should see the live camera image.
D. Add the Hugging Face skill
E. Configure Hugging Face
F. Query once
What should happen
Important
If you still get:
Attempting to read GetCurrentBitmapManaged while lockedthat usually means:
So for this test, make sure only Camera Device + Hugging Face are in the project.
2) Face-tracking setup using Camera Device skill with pan/tilt
This is the correct setup if you want the camera to physically follow a person.
Goal
Use the camera to detect a person and move pan/tilt servos.
A. Add Camera Device
If not already added:
B. Add pan/tilt servos
You need two servos connected to the EZ-B:
Typical ports:
(You can use different ports if needed.)
C. Add a servo control skill
If you want manual servo testing first:
This is important before using tracking.
D. Configure Camera Tracking
E. Start the camera and test
Best practice
For face-following, Object Detection is usually better than Vision Chat.
If you want it to track faces specifically, note:
3) Checking your Hugging Face token / provider settings step-by-step
This is the most likely reason for your
model_not_supportederror.What ARC needs
ARC only needs:
If Hugging Face says the model is not supported, it usually means the account/provider side needs adjustment.
A. Verify the token
Tip
Use a read token unless the skill documentation says otherwise.
B. Check if the model is gated
Some models require you to accept terms before use.
This is especially important for vision models.
C. Check provider availability
Your error says:
That means your account may not have an enabled inference provider for that model.
What to look for
On Hugging Face, check:
Practical advice
If a model gives
model_not_supported, try a model that is:But even then, provider support can vary over time.
D. Try the model page directly
To confirm whether Hugging Face can serve it at all:
Recommended order to test
Do these in this order:
Test 1 - Camera only
Test 2 - Camera + Object Detection
Test 3 - Vision Chat
Why you’re seeing two errors
model_not_supportedThis is Hugging Face saying the model is not available through your enabled provider.
GetCurrentBitmapManaged while lockedThis is ARC’s camera image being accessed while another process is already using it.
That usually means the project needs to be simplified before testing.

Quick question
Would you like me to give you:
If you want, I can also help you inspect the Hugging Face model page and token settings one screenshot at a time.
So I started with the 3 clean steps as suggested. Happy to report that everything worked. looked like opening a whole new project was best idea, along with latest huggingface update. I tried the object detection and face detection, and HF was able to report back what it was seeing.
I would like the click-by-click setup for the pan/tilt face tracking
Great - that narrows it down nicely. Since the clean project worked, the earlier issue was almost certainly a project/camera-lock conflict, and the latest Hugging Face update helped too.
Let’s set up pan/tilt face tracking in ARC step by step.
What you need
Camera DeviceskillClick-by-click pan/tilt face tracking setup
1) Add and test the servos first
Before camera tracking, make sure the servos move manually.
Add a servo control
d0d1Test movement
If you already have a servo skill set up, you can skip this part.
2) Open the Camera Device skill
3) Enable Object Detection
For face/person following, use Object Detection.
If you want the robot to follow a face specifically, the detection usually still works best as person.
4) Assign pan and tilt servos
Typical setup:
If there’s an option for relative tracking versus absolute tracking:
5) Set movement direction correctly
This is very important.
If the camera moves the wrong way:
Examples:
6) Set tracking behavior
Now tune the motion so it doesn’t jitter.
Look for these settings in the camera tracking section:
A good starting point:
7) Start tracking
Suggested simple starting settings
Use these as a baseline:
personCommon fixes
If the servos do nothing
If the servos move the wrong way
If the servos jitter
If tracking is slow

If you share a screenshot of your Camera Device skill tracking tab, I can mark exactly what to set.
