Spindle-Shaped

This model is trained using DenseNet121 over ConSeP dataset.

Data

The training dataset is from https://warwick.ac.uk/fac/cross_fac/tia/data/hovernet

wget https://warwick.ac.uk/fac/cross_fac/tia/data/hovernet/consep_dataset.zip\nunzip -q consep_dataset.zip\n

Preprocessing

After downloading this dataset,\npython script data_process.py from scripts folder can be used to preprocess and generate the final dataset for training.

python scripts/data_process.py --input /path/to/data/CoNSeP --output /path/to/data/CoNSePNuclei\n

After generating the output files, please modify the dataset_dir parameter specified in configs/train.json and configs/inference.json to reflect the output folder which contains new dataset.json.

Class values in dataset are

1 = other
2 = inflammatory
3 = healthy epithelial
4 = dysplastic/malignant epithelial
5 = fibroblast
6 = muscle
7 = endothelial

As part of pre-processing, the following steps are executed.

Crop and Extract each nuclei Image + Label (128x128) based on the centroid given in the dataset.
Combine classes 3 & 4 into the epithelial class and 5,6 & 7 into the spindle-shaped class.
Update the label index for the target nuclie based on the class value
Other cells which are part of the patch are modified to have label idex = 255

Example dataset.json in output folder:

{\n  \"training\": [\n    {\n      \"image\": \"/workspace/data/CoNSePNuclei/Train/Images/train_1_3_0001.png\",\n      \"label\": \"/workspace/data/CoNSePNuclei/Train/Labels/train_1_3_0001.png\",\n      \"nuclei_id\": 1,\n      \"mask_value\": 3,\n      \"centroid\": [\n        64,\n        64\n      ]\n    }\n  ],\n  \"validation\": [\n    {\n      \"image\": \"/workspace/data/CoNSePNuclei/Test/Images/test_1_3_0001.png\",\n      \"label\": \"/workspace/data/CoNSePNuclei/Test/Labels/test_1_3_0001.png\",\n      \"nuclei_id\": 1,\n      \"mask_value\": 3,\n      \"centroid\": [\n        64,\n        64\n      ]\n    }\n  ]\n}\n

TensorRT speedup

This bundle supports acceleration with TensorRT. The table below displays the speedup ratios observed on an A100 80G GPU. Please note that 32-bit precision models are benchmarked with tf32 weight format.

Where:

model computation means the speedup ratio of model's inference with a random input without preprocessing and postprocessing
end2end means run the bundle end-to-end with the TensorRT based model.
torch_tf32 and torch_amp are for the PyTorch models with or without amp mode.
trt_tf32 and trt_fp16 are for the TensorRT based models converted in corresponding precision.
speedup amp, speedup tf32 and speedup fp16 are the speedup ratios of corresponding models versus the PyTorch float32 model
amp vs fp16 is the speedup ratio between the PyTorch amp model and the TensorRT float16 based model.

This result is benchmarked under:

TensorRT: 10.3.0+cuda12.6

MONAI Bundle Commands

In addition to the Pythonic APIs, a few command line interfaces (CLI) are provided to interact with the bundle. The CLI supports flexible use cases, such as overriding configs at runtime and predefining arguments in a file.

For more details usage instructions, visit the MONAI Bundle Configuration Page.

Execute training:

python -m monai.bundle run --config_file configs/train.json\n

Please note that if the default dataset path is not modified with the actual path in the bundle config files, you can also override it by using --dataset_dir:

\n\">

python -m monai.bundle run --config_file configs/train.json --dataset_dir <actual dataset path>\n

Override the `train` config to execute multi-GPU training:

torchrun --standalone --nnodes=1 --nproc_per_node=2 -m monai.bundle run --config_file \"['configs/train.json','configs/multi_gpu_train.json']\"\n

Please note that the distributed training-related options depend on the actual running environment; thus, users may need to remove --standalone, modify --nnodes, or do some other necessary changes according to the machine used. For more details, please refer to pytorch's official tutorial.

Override the `train` config to execute evaluation with the trained model:

python -m monai.bundle run --config_file \"['configs/train.json','configs/evaluate.json']\"\n

Override the `train` config and `evaluate` config to execute multi-GPU evaluation:

torchrun --standalone --nnodes=1 --nproc_per_node=2 -m monai.bundle run --config_file \"['configs/train.json','configs/evaluate.json','configs/multi_gpu_evaluate.json']\"\n

Execute inference:

python -m monai.bundle run --config_file configs/inference.json\n

Execute inference with the TensorRT model:

python -m monai.bundle run --config_file \"['configs/inference.json', 'configs/inference_trt.json']\"\n
