# InternImage for Image Classification
This folder contains the implementation of the InternImage for image classification.
## Usage
### Install
- Clone this repo:
```bash
git clone https://github.com/OpenGVLab/InternImage.git
cd InternImage
```
- Create a conda virtual environment and activate it:
```bash
conda create -n internimage python=3.7 -y
conda activate internimage
```
- Install `CUDA>=10.2` with `cudnn>=7` following
the [official installation instructions](https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html)
- Install `PyTorch>=1.8.0` and `torchvision>=0.9.0` with `CUDA>=10.2`:
For examples, to install torch==1.11 with CUDA==11.3:
```bash
pip install torch==1.11.0+cu113 torchvision==0.12.0+cu113 -f https://download.pytorch.org/whl/torch_stable.html
```
- Install `timm==0.6.11` and `mmcv-full==1.5.0`:
```bash
pip install -U openmim
mim install mmcv-full==1.5.0
pip install timm==0.6.11 mmdet==2.28.1
```
- Install other requirements:
```bash
pip install opencv-python termcolor yacs pyyaml scipy
```
- Compiling CUDA operators
```bash
cd ./ops_dcnv3
sh ./make.sh
# unit test (should see all checking is True)
python test.py
```
### Data preparation
We use standard ImageNet dataset, you can download it from http://image-net.org/. We provide the following two ways to
load data:
- For standard folder dataset, move validation images to labeled sub-folders. The file structure should look like:
```bash
$ tree data
imagenet
├── train
│ ├── class1
│ │ ├── img1.jpeg
│ │ ├── img2.jpeg
│ │ └── ...
│ ├── class2
│ │ ├── img3.jpeg
│ │ └── ...
│ └── ...
└── val
├── class1
│ ├── img4.jpeg
│ ├── img5.jpeg
│ └── ...
├── class2
│ ├── img6.jpeg
│ └── ...
└── ...
```
- To boost the slow speed when reading images from massive small files, we also support zipped ImageNet, which includes
four files:
- `train.zip`, `val.zip`: which store the zipped folder for train and validate splits.
- `train.txt`, `val.txt`: which store the relative path in the corresponding zip file and ground truth
label. Make sure the data folder looks like this:
```bash
$ tree data
data
└── ImageNet-Zip
├── train_map.txt
├── train.zip
├── val_map.txt
└── val.zip
$ head -n 5 meta_data/val.txt
ILSVRC2012_val_00000001.JPEG 65
ILSVRC2012_val_00000002.JPEG 970
ILSVRC2012_val_00000003.JPEG 230
ILSVRC2012_val_00000004.JPEG 809
ILSVRC2012_val_00000005.JPEG 516
$ head -n 5 meta_data/train.txt
n01440764/n01440764_10026.JPEG 0
n01440764/n01440764_10027.JPEG 0
n01440764/n01440764_10029.JPEG 0
n01440764/n01440764_10040.JPEG 0
n01440764/n01440764_10042.JPEG 0
```
- For ImageNet-22K dataset, make a folder named `fall11_whole` and move all images to labeled sub-folders in this
folder. Then download the train-val split
file ([ILSVRC2011fall_whole_map_train.txt](https://github.com/SwinTransformer/storage/releases/download/v2.0.1/ILSVRC2011fall_whole_map_train.txt)
& [ILSVRC2011fall_whole_map_val.txt](https://github.com/SwinTransformer/storage/releases/download/v2.0.1/ILSVRC2011fall_whole_map_val.txt))
, and put them in the parent directory of `fall11_whole`. The file structure should look like:
```bash
$ tree imagenet22k/
imagenet22k/
└── fall11_whole
├── n00004475
├── n00005787
├── n00006024
├── n00006484
└── ...
```
### Evaluation
To evaluate a pre-trained `InternImage` on ImageNet val, run:
```bash
python -m torch.distributed.launch --nproc_per_node <num-of-gpus-to-use> --master_port 12345 main.py --eval \
--cfg <config-file> --resume <checkpoint> --data-path <imagenet-path>
```
For example, to evaluate the `InternImage-B` with a single GPU:
```bash
python -m torch.distributed.launch --nproc_per_node 1 --master_port 12345 main.py --eval \
--cfg configs/internimage_b_1k_224.yaml --resume internimage_b_1k_224.pth --data-path <imagenet-path>
```
### Training from scratch on ImageNet-1K
To train an `InternImage` on ImageNet from scratch, run:
```bash
python -m torch.distributed.launch --nproc_per_node <num-of-gpus-to-use> --master_port 12345 main.py \
--cfg <config-file> --data-path <imagenet-path> [--batch-size <batch-size-per-gpu> --output <output-directory> --tag <job-tag>]
```
### Manage jobs with Srun.
For example, to train `InternImage` with 8 GPU on a single node for 300 epochs, run:
`InternImage-T`:
```bash
GPUS=8 sh train_in1k.sh <partition> <job-name> configs/internimage_t_1k_224.yaml --resume internimage_t_1k_224.pth --eval
```
`InternImage-S`:
```bash
GPUS=8 sh train_in1k.sh <partition> <job-name> configs/internimage_s_1k_224.yaml --resume internimage_s_1k_224.pth --eval
```
`InternImage-XL`:
```bash
GPUS=8 sh train_in1k.sh <partition> <job-name> configs/internimage_xl_22kto1k_384.pth --resume internimage_xl_22kto1k_384.pth --eval
```
<!--
### Test pretrained model on ImageNet-22K
For example, to evaluate the `InternImage-L-22k`:
```bash
python -m torch.distributed.launch --nproc_per_node <num-of-gpus-to-use> --master_port 12345 main.py \
--cfg configs/internimage_xl_22k_192to384.yaml --data-path <imagenet-path> [--batch-size <batch-size-per-gpu> --output <output-directory>] \
--resume internimage_xl_22k_192to384.pth --eval
``` -->
<!-- ### Fine-tuning from a ImageNet-22K pre-trained model
For example, to fine-tune a `InternImage-XL-22k` model pre-trained on ImageNet-22K:
```bashs
GPUS=8 sh train_in1k.sh <partition> <job-name> configs/intern_image_.yaml --pretrained intern_image_b.pth --eval
python -m torch.distributed.launch --nproc_per_node 8 --master_port 12345 main.py \
--cfg configs/.yaml --pretrained swin_base_patch4_window7_224_22k.pth \
--data-path <imagenet-path> --batch-size 64 --accumulation-steps 2 [--use-checkpoint]
``` -->
### Export
To export `InternImage-T` from PyTorch to ONNX, run:
```shell
python export.py --model_name internimage_t_1k_224 --ckpt_dir /path/to/ckpt/dir --onnx
```
To export `InternImage-T` from PyTorch to TensorRT, run:
```shell
python export.py --model_name internimage_t_1k_224 --ckpt_dir /path/to/ckpt/dir --trt
```
