resnet50-res512-all

ResNet (Residual Network) is a convolutional neural network that democratized the concepts of residual learning and skip connections. This enables to train much deeper models.

This model was trained on the datasets pc-nih-rsna-siim-vin at a 512x512 resolution.

How to use

Here is how to use this model to classify an image of xray:

Note: Each pretrained model has 18 outputs. The all model has every output trained. However, for the other weights some targets are not trained and will predict randomly becuase they do not exist in the training dataset. The only valid outputs are listed in the field {dataset}.pathologies on the dataset that corresponds to the weights.

Benchmarks of the modes are here: BENCHMARKS.md

python

import urllib.request

import skimage
import torch
import torch.nn.functional as F
import torchvision
import torchvision.transforms

import torchxrayvision as xrv

model_name = "resnet50-res512-all"

img_url = "https://huggingface.co/spaces/torchxrayvision/torchxrayvision-classifier/resolve/main/16747_3_1.jpg"
img_path = "xray.jpg"
urllib.request.urlretrieve(img_url, img_path)

model = xrv.models.get_model(model_name, from_hf_hub=True)

img = skimage.io.imread(img_path)
img = xrv.datasets.normalize(img, 255)

# Check that images are 2D arrays
if len(img.shape) > 2:
    img = img[:, :, 0]
if len(img.shape) < 2:
    print("error, dimension lower than 2 for image")

# Add color channel
img = img[None, :, :]

transform = torchvision.transforms.Compose([xrv.datasets.XRayCenterCrop()])

img = transform(img)

with torch.no_grad():
    img = torch.from_numpy(img).unsqueeze(0)
    preds = model(img).cpu()
    output = {
        k: float(v)
        for k, v in zip(xrv.datasets.default_pathologies, preds[0].detach().numpy())
    }
print(output)
