Ahcore comes with several models included, check the model zoo for more information:

• Tissue/background segmentation in H&Es

To train a model, first make sure ahcore is installed:

git clone https://github.com/NKI-AI/ahcore.git && cd ahcore && pip install -e .

Next, make sure that the environmental variables are set correctly. We are using dotenv for this but you can set the variables themselves. Check tools/.env.example to see which variables you need to set. If you use dotenv, you will need to make a copy cp tools/.env.example tools/.env and fill in the correct values.

Next, you will need to create manifest, and once done, it's often beneficial to copy the data to a local drive, if its not there yet. You can use the ahcore data copy-data-from-manifest tool for this.
