Model Details

Model Usage

Image Classification

python 
from urllib.request import urlopen
from PIL import Image
import jax

import jaxnn

img = Image.open(urlopen(
    'https://huggingface.co/datasets/huggingface/cats-image/resolve/main/cats_image.jpeg'
))

model = jaxnn.create_model('resnet50.a1_in1k', pretrained=True)
model.eval()

# get model specific transforms (normalization, resize)
data_config = jaxnn.data.resolve_model_data_config(model)
transforms = jaxnn.data.create_transform(**data_config, is_training=False)

output = model(jax.numpy.expand_dims(transforms(img), 0))  # unsqueeze single image into batch of 1

top5_probabilities, top5_class_indices = jax.lax.top_k(jax.nn.softmax(output, axis=-1) * 100, k=5)

Feature Map Extraction

python 
from urllib.request import urlopen
from PIL import Image
import jax

import jaxnn

img = Image.open(urlopen(
    'https://huggingface.co/datasets/huggingface/cats-image/resolve/main/cats_image.jpeg'
))

model = jaxnn.create_model(
    'resnet50.a1_in1k',
    pretrained=True,
    features_only=True,
)
model.eval()

# get model specific transforms (normalization, resize)
data_config = jaxnn.data.resolve_model_data_config(model)
transforms = jaxnn.data.create_transform(**data_config, is_training=False)

output = model(jax.numpy.expand_dims(transforms(img), 0))  # jax.numpy.expand_dims single image into batch of 1

for o in output:
    # print shape of each feature map in output in format [Batch, Height, Width, Channels]
    # e.g.:
    #  (1, 112, 112, 64)
    #  (1, 56, 56, 64)
    #  (1, 28, 28, 128)
    #  (1, 14, 14, 256)
    #  (1, 7, 7, 512)

    print(o.shape)

Image Embeddings

python 
from urllib.request import urlopen
from PIL import Image
import jax

import jaxnn

img = Image.open(urlopen(
    'https://huggingface.co/datasets/huggingface/cats-image/resolve/main/cats_image.jpeg'
))

model = jaxnn.create_model(
    'resnet50.a1_in1k',
    pretrained=True,
    num_classes=0,  # remove classifier nn.Linear
)
model.eval()

# get model specific transforms (normalization, resize)
data_config = jaxnn.data.resolve_model_data_config(model)
transforms = jaxnn.data.create_transform(**data_config, is_training=False)

output = model(jax.numpy.expand_dims(transforms(img), 0))   # output is (batch_size, num_features) shaped Array

# or equivalently (without needing to set num_classes=0)

output = model.forward_features(jax.numpy.expand_dims(transforms(img), 0))
# output is unpooled, a (1, 7, 7, 512) shaped tensor

📝 Limitations & Considerations

  • â€ĸ Benchmark scores may vary based on evaluation methodology and hardware configuration.
  • â€ĸ VRAM requirements are estimates; actual usage depends on quantization and batch size.
  • â€ĸ FNI scores are relative rankings and may change as new models are added.
  • ⚠ License Unknown: Verify licensing terms before commercial use.
