# ResNet-50 v1.5 |
|
|
|
ResNet model pre-trained on ImageNet-1k at resolution 224x224. It was introduced in the paper [Deep Residual Learning for Image Recognition](https://arxiv.org/abs/1512.03385) by He et al. |
|
|
|
Disclaimer: The team releasing ResNet did not write a model card for this model so this model card has been written by the Hugging Face team. |

|
## Model description |
|
|
|
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 is ResNet v1.5, which differs from the original model: in the bottleneck blocks which require downsampling, v1 has stride = 2 in the first 1x1 convolution, whereas v1.5 has stride = 2 in the 3x3 convolution. This difference makes ResNet50 v1.5 slightly more accurate (\~0.5% top1) than v1, but comes with a small performance drawback (~5% imgs/sec) according to [Nvidia](https://catalog.ngc.nvidia.com/orgs/nvidia/resources/resnet_50_v1_5_for_pytorch). |

## Intended uses & limitations |
|
|
|
You can use the raw model for image classification. See the [model hub](https://huggingface.co/models?search=resnet) to look for |
|
fine-tuned versions on a task that interests you. |
|
|
|
### How to use |
|
|
|
Here is how to use this model to classify an image of the COCO 2017 dataset into one of the 1,000 ImageNet classes: |
|
|
|
```python |
|
from transformers import AutoFeatureExtractor, ResNetForImageClassification |
|
import torch |
|
from datasets import load_dataset |
|
|
|
dataset = load_dataset("huggingface/cats-image") |
|
image = dataset["test"]["image"][0] |
|
|
|
feature_extractor = AutoFeatureExtractor.from_pretrained("microsoft/resnet-50") |
|
model = ResNetForImageClassification.from_pretrained("microsoft/resnet-50") |
|
|
|
inputs = feature_extractor(image, return_tensors="pt") |
|
|
|
with torch.no_grad(): |
|
logits = model(**inputs).logits |
|
|
|
# model predicts one of the 1000 ImageNet classes |
|
predicted_label = logits.argmax(-1).item() |
|
print(model.config.id2label[predicted_label]) |
|
``` |
|
|
|
