Pytorch extension for openml-python API. This library provides a simple way to run your Pytorch models on OpenML tasks.
For a more native experience, PyTorch itself provides OpenML integrations for some tasks. You can find more information here.
pip install openml-pytorch

Set the API key for OpenML from the command line:
openml configure apikey <your API key>Import openML libraries
import torch.nn
import torch.optim
import openml_pytorch.config

from openml_pytorch.trainer import convert_to_rgbCreate a pytorch model and get a task from openML
model = torchvision.models.efficientnet_b0(num_classes=200)
# Download the OpenML task for tiniest imagenet

openml_pytorch.config.trainer = trainerRun the model on the task
run = openml.runs.run_model_on_task(model, task, avoid_duplicate_runs=False)
run.publish()
print('URL for run: %s/run/%d' % (openml.config.server, run.run_id))Note: The input layer of the network should be compatible with OpenML data output shape. Please check examples for more information.
Additionally, if you want to publish the run with onnx file, then you must call openml_pytorch.add_onnx_to_run() immediately before run.publish().
run = openml_pytorch.add_onnx_to_run(run)
