More detailed test of sklearn.linear_model

[lesteve]

sklearn.linear_model.tests.test_base

sometimes pass sometimes not.

This seems to pass consistently:

node --experimental-fetch scikit-learn-pytest.js --pyargs sklearn.linear_model.tests.test_base -v -k 'not regression_multiple_outcome'

This sometimes passes, sometimes hangs, sometimes errors with an error that does not make sense, sometimes with a Pyodide stack-trace

node --experimental-fetch scikit-learn-pytest.js --pyargs sklearn.linear_model.tests.test_base -v -k 'regression_multiple_outcome'

Example of stack-trace:

The cause of the fatal error was:

sklearn.linear_model.tests.test_ransac

Sometimes pass sometimes not.

This seems to consistently pass:

node --experimental-fetch scikit-learn-pytest.js --pyargs sklearn.linear_model.tests.test_ransac -v -k 'not test_ransac_final_model_fit_sample_weight'

node --experimental-fetch scikit-learn-pytest.js --pyargs sklearn.linear_model.tests.test_ransac -v -k 'test_ransac_final_model_fit_sample_weight'
