[python-package] Create Dataset from multiple data files (#4089) * [python-package] create Dataset from sampled data. * [python-package] create Dataset from List[Sequence]. 1. Use random access for data sampling 2. Support read data from multiple input files 3. Read data in batch so no need to hold all data in memory * [python-package] example: create Dataset from multiple HDF5 file. * fix: revert is_class implementation for seq * fix: unwanted memory view reference for seq * fix: seq is_class accepts sklearn matrices * fix: requirements for example * fix: pycode * feat: print static code linting stage * fix: linting: avoid shell str regex conversion * code style: doc style * code style: isort * fix ci dependency: h5py on windows * [py] remove rm files in test seq https://github.com/microsoft/LightGBM/pull/4089#discussion_r612929623 * docs(python): init_from_sample summary https://github.com/microsoft/LightGBM/pull/4089#discussion_r612903389 * remove dataset dump sample data debugging code. * remove typo fix. Create separate PR for this. * fix typo in src/c_api.cpp Co-authored-by: James Lamb <jaylamb20@gmail.com> * style(linting): py3 type hint for seq * test(basic): os.path style path handling * Revert "feat: print static code linting stage" This reverts commit 10bd79f7f8258bea8e61c3abb8c9c7e4456a916d. * feat(python): sequence on validation set * minor(python): comment * minor(python): test option hint * style(python): fix code linting * style(python): add pydoc for ref_dataset * doc(python): sequence Co-authored-by: shiyu1994 <shiyu_k1994@qq.com> * revert(python): sequence class abc * chore(python): remove rm_files * Remove useless static_assert. * refactor: test_basic test for sequence. * fix lint complaint. * remove dataset._dump_text in sequence test. * Fix reverting typo fix. * Apply suggestions from code review Co-authored-by: James Lamb <jaylamb20@gmail.com> * Fix type hint, code and doc style. * fix failing test_basic. * Remove TODO about keep constant in sync with cpp. * Install h5py only when running python-examples. * Fix lint complaint. * Apply suggestions from code review Co-authored-by: James Lamb <jaylamb20@gmail.com> * Doc fixes, remove unused params_str in __init_from_seqs. * Apply suggestions from code review Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Remove unnecessary conda install in windows ci script. * Keep param as example in dataset_from_multi_hdf5.py * Add _get_sample_count function to remove code duplication. * Use batch_size parameter in generate_hdf. * Apply suggestions from code review Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Fix after applying suggestions. * Fix test, check idx is instance of numbers.Integral. * Update python-package/lightgbm/basic.py Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Expose Sequence class in Python-API doc. * Handle Sequence object not having batch_size. * Fix isort lint complaint. * Apply suggestions from code review Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Update docstring to mention Sequence as data input. * Remove get_one_line in test_basic.py * Make Sequence an abstract class. * Reduce number of tests for test_sequence. * Add c_api: LGBM_SampleCount, fix potential bug in LGBMSampleIndices. * empty commit to trigger ci * Apply suggestions from code review Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Rename to LGBM_GetSampleCount, change LGBM_SampleIndices out_len to int32_t. Also rename total_nrow to num_total_row in c_api.h for consistency. * Doc about Sequence in docs/Python-Intro.rst. * Fix: basic.py change LGBM_SampleIndices out_len to int32. * Add create_valid test case with Dataset from Sequence. * Apply suggestions from code review Co-authored-by: Nikita Titov <nekit94-08@mail.ru> * Apply suggestions from code review Co-authored-by: shiyu1994 <shiyu_k1994@qq.com> * Remove no longer used DEFAULT_BIN_CONSTRUCT_SAMPLE_CNT. * Update python-package/lightgbm/basic.py Co-authored-by: Nikita Titov <nekit94-08@mail.ru> Co-authored-by: Willian Zhang <willian@willian.email> Co-authored-by: Willian Z <Willian@Willian-Zhang.com> Co-authored-by: James Lamb <jaylamb20@gmail.com> Co-authored-by: shiyu1994 <shiyu_k1994@qq.com> Co-authored-by: Nikita Titov <nekit94-08@mail.ru>
