Jiaming Yuan	3a4f51f39f	Avoid calling CUDA code on CPU for linear model. (#7154 )	2021-09-01 10:45:31 +08:00
Philip Hyunsu Cho	9c9070aea2	Use pytest conventions consistently (#6337 ) * Do not derive from unittest.TestCase (not needed for pytest) * assertRaises -> pytest.raises * Simplify test_empty_dmatrix with test parametrization * setUpClass -> setup_class, tearDownClass -> teardown_class * Don't import unittest; import pytest * Use plain assert * Use parametrized tests in more places * Fix test_gpu_with_sklearn.py * Put back run_empty_dmatrix_reg / run_empty_dmatrix_cls * Fix test_eta_decay_gpu_hist * Add parametrized tests for monotone constraints * Fix test names * Remove test parametrization * Revise test_slice to be not flaky	2020-11-19 17:00:15 -08:00
Jiaming Yuan	184e2eac7d	Add period to evaluation monitor. (#6348 )	2020-11-10 07:47:48 +08:00
Jiaming Yuan	7d93932423	Better message when no GPU is found. (#5594 )	2020-04-26 10:00:57 +08:00
Jiaming Yuan	61286c6e8f	Fix wrapping GPU ID and prevent data copying. (#5160 ) * Removed some data copying. * Make sure gpu_id is valid before any configuration is carried out.	2019-12-27 16:51:08 +08:00
Jiaming Yuan	3136185bc5	JSON configuration IO. (#5111 ) * Add saving/loading JSON configuration. * Implement Python pickle interface with new IO routines. * Basic tests for training continuation.	2019-12-15 17:31:53 +08:00
Jiaming Yuan	c589eff941	De-duplicate GPU parameters. (#4454 ) * Only define `gpu_id` and `n_gpus` in `LearnerTrainParam` * Pass LearnerTrainParam through XGBoost vid factory method. * Disable all GPU usage when GPU related parameters are not specified (fixes XGBoost choosing GPU over aggressively). * Test learner train param io. * Fix gpu pickling.	2019-05-29 11:55:57 +08:00
