Current implementation silently returns zero when input string is "inf", "-inf", or "nan" when compiled with VS2017, so instead just explicitly check for these values and fail if there is no match. No attempt to optimise string allocations in this implementation since it is usually rarely invoked. * Dummy commit to trigger CI * Also handle -nan in double parsing method * Update include/LightGBM/utils/common.h Remove trailing whitespace to pass linting tests Co-authored-by: Nikita Titov <[email protected]> Co-authored-by: matthew-peacock <[email protected]> Co-authored-by: Guolin Ke <[email protected]> Co-authored-by: Nikita Titov <[email protected]> * [dask] remove unused imports from typing (#4079) * Range check for DCG position discount lookup (#4069) * Add check to prevent out of index lookup in the position discount table.

This reverts commit 3981b34. * Add data file name to debug logging. * Move log line to a place where it is output even when query IDs are read from a separate file. * Also add the out-of-range check to rank metrics. * Perform check after number of queries is initialized. * Update * [ci] upgrade R CI scripts to work on Ubuntu 20.04 (#4084) * [ci] install additional LaTeX packages in R CI jobs * update autoconf version * bump upper limit on package size to 100 * [SWIG] Add streaming data support + cpp tests (#3997) * [feature] Add ChunkedArray to SWIG * Add ChunkedArray * Add ChunkedArray_API_extensions.i * Add SWIG class wrappers * Address some review comments * Fix linting issues * Move test to tests/test_ChunkedArray_manually.cpp * Add test note * Move ChunkedArray to include/LightGBM/utils/ * Declare more explicit types of ChunkedArray in the SWIG API. * Port ChunkedArray tests to googletest * Please C++ linter * Address StrikerRUS' review comments * Update SWIG doc & disable ChunkedArray<int64_t> * Use CHECK_EQ instead of assert * Change include order (linting) * Rename ChunkedArray -> chunked_array files * Change header guards * Address last comments from StrikerRUS * store all CMake files in one place (#4087) * v3.2.0 release (#3872) * Update VERSION.txt * update appveyor.yml and configure * fix Appveyor builds Co-authored-by: James Lamb <[email protected]> Co-authored-by: Nikita Titov <[email protected]> Co-authored-by: StrikerRUS <[email protected]> * [ci] Bump version for development (#4094) * Update .appveyor.yml * Update cran-comments.md * Update VERSION.txt * update configure Co-authored-by: James Lamb <[email protected]> * [ci] fix flaky Azure Pipelines jobs (#4095) * Update test.sh * Update setup.sh * Update .vsts-ci.yml * Update test.sh * Update setup.sh * Update .vsts-ci.yml * Update setup.sh * Update setup.sh Co-authored-by: Subham Agrawal <[email protected]> Co-authored-by: James Lamb <[email protected]> Co-authored-by: shiyu1994 <[email protected]> Co-authored-by: Nikita Titov <[email protected]> Co-authored-by: jmoralez <[email protected]> Co-authored-by: marcelonieva7 <[email protected]> Co-authored-by: Philip Hyunsu Cho <[email protected]> Co-authored-by: Deddy Jobson <[email protected]> Co-authored-by: Alberto Ferreira <[email protected]> Co-authored-by: mjmckp <[email protected]> Co-authored-by: matthew-peacock <[email protected]> Co-authored-by: Guolin Ke <[email protected]> Co-authored-by: ashok-ponnuswami-msft <[email protected]> Co-authored-by: StrikerRUS <[email protected]> * Apply suggestions from code review Co-authored-by: Nikita Titov <[email protected]> Co-authored-by: James Lamb <[email protected]> Co-authored-by: Subham Agrawal <[email protected]> Co-authored-by: shiyu1994 <[email protected]> Co-authored-by: Nikita Titov <[email protected]> Co-authored-by: jmoralez <[email protected]> Co-authored-by: marcelonieva7 <[email protected]> Co-authored-by: Philip Hyunsu Cho <[email protected]> Co-authored-by: Deddy Jobson <[email protected]> Co-authored-by: Alberto Ferreira <[email protected]> Co-authored-by: mjmckp <[email protected]> Co-authored-by: matthew-peacock <[email protected]> Co-authored-by: Guolin Ke <[email protected]> Co-authored-by: ashok-ponnuswami-msft <[email protected]> Co-authored-by: StrikerRUS <[email protected]>

As of #3994 , it's possible to give the estimators in
lightgbm.daskan exact set of worker IPs + ports to use for distributed training. This is done by providing a parametermachines, a string with a comma-delimited list likeip1:port1,ip2:port2.If you accidentally include duplicates in this list, the error you get today is not very informative:
This PR proposes catching this case and throwing a more informative error.
Notes for Reviewers
In this case, "duplicates" refers to duplicate
ip-portpairs. It is possible and very common to run multiple Dask workers on one physical machine. In those cases, it'smachinesmight look like thisIn #4057, I mentioned that it was probably possible to even further reduce the risk of the type of job failure that cause #4057. This could be done with something like this: 9442bdf.
However, after thinking about it, I now think we shouldn't do that. If a change results in this error happening a lot more frequently than I expect it to (1 in ever 4 billion runs), then we should see CI failing more frequently. I think it's desirable for that to happen so we know something is wrong.
