Description

This PR adds a data loader for classifications from the timm Python package.

Type of change

  • New feature (non-breaking change which adds functionality)

How has this change been tested, please provide a testcase or example of how you tested the change?

You can test the API using the following code:

import timm
import torch
from PIL import Image
from timm.data import resolve_data_config
from timm.data.transforms_factory import create_transform
import supervision as sv

# Load from Hub 馃敟
model = timm.create_model(
    'hf-hub:nateraw/resnet50-oxford-iiit-pet',
    pretrained=True
)

# Set model to eval mode for inference
model.eval()

# Create Transform
transform = create_transform(**resolve_data_config(model.pretrained_cfg, model=model))

# Get the labels from the model config
labels = model.pretrained_cfg['label_names']
top_k = min(len(labels), 5)

# Use your own image file here...
image = Image.open('./annotated_image.jpg').convert('RGB')

# Process PIL image with transforms and add a batch dimension
x = transform(image).unsqueeze(0)

# Pass inputs to model forward function to get outputs
out = model(x)

results = sv.Classifications.from_timm(out)

print(results)

The variable names and usage within the 'ultralytics' and 'timm' functions were updated for improved code readability. The docstrings were also refined to better explain the function parameters. Instances where YOLO was redundantly called were also eliminated.
Adjustments have been made to the import statements in the 'core.py' file of the 'classification' module.
