Hi! I have a code for recognizing road signs. Everything is implemented on Raspberry Pi 4. The code itself is below:
```auto
import requests
import cv2
import numpy as np
from picamera import PiCamera
from roboflow import Roboflow
# ΠΠ½ΠΈΡΠΈΠ°Π»ΠΈΠ·ΠΈΡΡΠ΅ΠΌ ΠΊΠ»ΠΈΠ΅Π½Ρ Roboflow
rf = Roboflow(api_key="my_api_key")
project = rf.workspace().project("project_name")
model = project.version(1).model
# ΠΠ½ΠΈΡΠΈΠ°Π»ΠΈΠ·Π°ΡΠΈΡ ΠΊΠ°ΠΌΠ΅ΡΡ
camera = PiCamera()
# ΠΠ°Π³ΡΡΠΆΠ°Π΅ΠΌ ΠΊΠ»Π°ΡΡΡ Π΄Π»Ρ Π²ΡΠ²ΠΎΠ΄Π° ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΠΎΠ²
classes = ['Stop', '60 km/h', '40 km/h', 'Forward']
# ΠΠ°Ρ
Π²Π°ΡΡΠ²Π°Π΅ΠΌ Π²ΠΈΠ΄Π΅ΠΎΠΏΠΎΡΠΎΠΊ Ρ ΠΊΠ°ΠΌΠ΅ΡΡ
camera.start_preview()
while True:
# Π‘Π½ΠΈΠΌΠ°Π΅ΠΌ ΡΡΠ΅ΠΉΠΌ Ρ ΠΊΠ°ΠΌΠ΅ΡΡ ΠΈ ΡΠΎΡ
ΡΠ°Π½ΡΠ΅ΠΌ Π΅Π³ΠΎ
camera.capture('frame.jpg')
# ΠΠ°Π³ΡΡΠΆΠ°Π΅ΠΌ ΡΡΠ΅ΠΉΠΌ ΠΈ ΠΈΠ·ΠΌΠ΅Π½ΡΠ΅ΠΌ Π΅Π³ΠΎ ΡΠ°Π·ΠΌΠ΅Ρ
image = cv2.imread('frame.jpg')
image = cv2.resize(image, (300, 300))
# ΠΠΎΠ½Π²Π΅ΡΡΠΈΡΡΠ΅ΠΌ ΠΈΠ·ΠΎΠ±ΡΠ°ΠΆΠ΅Π½ΠΈΠ΅ Π² ΡΠΎΡΠΌΠ°Ρ RGB
image_rgb = cv2.cvtColor(image, cv2.COLOR_BGR2RGB)
# ΠΡΠ΅Π΄ΡΠΊΠ°Π·ΡΠ²Π°Π΅ΠΌ Π½Π° ΠΈΠ·ΠΎΠ±ΡΠ°ΠΆΠ΅Π½ΠΈΠΈ
result = model.predict(image_rgb)
# ΠΠ·Π²Π»Π΅ΠΊΠ°Π΅ΠΌ ΠΈΠ½ΡΠΎΡΠΌΠ°ΡΠΈΡ ΠΎ Π΄ΠΎΡΠΎΠΆΠ½ΡΡ
Π·Π½Π°ΠΊΠ°Ρ
ΠΈΠ· ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΠ°
detections = result.predictions
for detection in detections:
class_name = detection.label
confidence = detection.confidence
box = detection.bounding_box
# ΠΠ·Π²Π»Π΅ΠΊΠ°Π΅ΠΌ ΠΊΠΎΠΎΡΠ΄ΠΈΠ½Π°ΡΡ ΠΏΡΡΠΌΠΎΡΠ³ΠΎΠ»ΡΠ½ΠΈΠΊΠ° ΠΈ Π΄Π΅Π»Π°Π΅ΠΌ ΠΏΡΠ΅ΠΎΠ±ΡΠ°Π·ΠΎΠ²Π°Π½ΠΈΡ ΡΠΎΠΎΡΠ²Π΅ΡΡΡΠ²ΡΡΡΠΈΠΌ ΠΎΠ±ΡΠ°Π·ΠΎΠΌ
# Π ΠΈΡΡΠ΅ΠΌ ΠΏΡΡΠΌΠΎΡΠ³ΠΎΠ»ΡΠ½ΠΈΠΊ ΠΈ ΡΠ΅ΠΊΡΡ Π½Π° ΠΈΠ·ΠΎΠ±ΡΠ°ΠΆΠ΅Π½ΠΈΠΈ
# ΠΡΠ²ΠΎΠ΄ΠΈΠΌ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ Π½Π° ΡΠΊΡΠ°Π½
cv2.imshow("Road Sign Detection", image)
# ΠΡΡ
ΠΎΠ΄ ΠΈΠ· ΡΠΈΠΊΠ»Π° ΠΏΠΎ Π½Π°ΠΆΠ°ΡΠΈΡ ΠΊΠ»Π°Π²ΠΈΡΠΈ 'q'
if cv2.waitKey(1) & 0xFF == ord('q'):
break
# ΠΠ°ΠΊΡΡΠ²Π°Π΅ΠΌ ΠΎΠΊΠ½Π° ΠΈ ΠΎΡΠ²ΠΎΠ±ΠΎΠΆΠ΄Π°Π΅ΠΌ ΡΠ΅ΡΡΡΡΡ ΠΊΠ°ΠΌΠ΅ΡΡ
cv2.destroyAllWindows()
camera.stop_preview()
```
But I get an error and I donβt understand which correct attribute is needed here.
```auto
Traceback (most recent call last): File "/home/rasberrypi/Desktop/ΠΡΠΎΠ΅ΠΊΡ 3/ai17.py",
line 38, in class_name = detection.label
AttributeError: 'Prediction' object has no attribute 'label'
```
**The error itself occurs when I show the desired road sign to the camera (that is, at the recognition stage)**

Your code seems to be well-structured for running inference on a Raspberry Pi using Roboflow. However, it seems like the code is incomplete, as the last line is cut off.
Hereβs a similar code snippet from the extracts that might help you:
```python
from roboflow import Roboflow
rf = Roboflow(api_key="API_KEY")
project = rf.workspace().project("PROJECT_NAME")
model = project.version(MODEL_VERSION, local="http://localhost:9001").model
# infer on a local image
print(model.predict("your_image.jpg", confidence=40, overlap=30).json())
# visualize your prediction
# model.predict("your_image.jpg", confidence=40, overlap=30).save("prediction.jpg")
# infer on an image hosted elsewhere
# print(model.predict("URL_OF_YOUR_IMAGE", hosted=True, confidence=40, overlap=30).json())
```
[Source](https://roboflow.com/how-to-deploy/yolov5-raspberry-pi)
In your case, you might want to replace `"your_image.jpg"` with the image captured from your camera. Also, you might want to adjust the `confidence` and `overlap` parameters according to your needs.
For the incomplete part of your code, if youβre trying to break the loop when a certain key is pressed, you can use something like this:
```python
if cv2.waitKey(1) & 0xFF == ord('q'):
break
```
This will break the loop when βqβ is pressed.
Please note that the code snippets provided are based on the information extracts and might need to be adjusted to fit your specific use case.

Also tried attributes: class/classes/class\_id/label
roboflow ver. 1.1.12
Python 3.9

Hi @Yashamaskaev
Sorry to hear youβre having trouble. The hosted inference API, which the Roboflow Python package uses, returns the following format. The class name is returned in a property called `class` under an array `predictions`.
If you already tried this, there might be another issue, so could you add a print statement, below that to see what the model result is?
