* Define default ctors for gpair.
Fix clang warning:
Definition of implicit copy assignment operator for 'GradientPairInternal<float>' is
deprecated because it has a user-declared copy constructor
We can handle loading the pickle on a CPU-only machine if the XGBoost is built with CUDA
enabled (Linux and Windows PyPI package), but not if the distribution is CPU-only (macOS
PyPI package).
* Support null value in CUDA array interface.
- Fix for potential null value in array interface.
- Fix incorrect check on mask stride.
* Simple tests.
* Extract mask.
* [R] Use new interface for creating DMatrix from CSR.
- CSC is still using the old API.
The old API is not aware of `nthread` parameter, which makes DMatrix to use all available
thread during construction and during transformation lie `SparsePage` -> `CSCPage`.
* Thrust 1.17 removes the experimental/pinned_allocator.
When xgboost is brought into a large project it can
be compiled against Thrust 1.17+ which don't offer
this experimental allocator.
To ensure that going forward xgboost works in all environments we provide a xgboost namespaced version of
the pinned_allocator that previously was in Thrust.
* Configuration for init estimation.
* Check whether the model needs configuration based on const attribute `ModelFitted`
instead of a mutable state.
* Add parameter `boost_from_average` to tell whether the user has specified base score.
* Add tests.
* Intoducing Column Wise Hist Building
* linting
* more linting
* bug fixing
* Removing column samping optimization for a while to simplify the review process.
* linting
* Removing unnecessary changes
* Use DispatchBinType in hist_util.cc
* Adding force_read_by column flag to buildhist. Adding tests for column wise buiilhist.
* Introducing new dispatcher for compile time flags in hist building
* fixing bug with using of DispatchBinType
* Fixing building
* Merging with master branch
