"""Training on a GPU cluster.
|
|
|
|
This will train a small dataset on a distributed GPU cluster.
|
|
|
|
Test owner: krfricke
|
|
|
|
Acceptance criteria: Should run through and report final results.
|
|
|
|
Notes: The test will report output such as this:
|
|
```
|
|
[05:14:49] WARNING: ../src/gbm/gbtree.cc:350: Loading from a raw memory buffer
|
|
on CPU only machine. Changing tree_method to hist.
|
|
[05:14:49] WARNING: ../src/learner.cc:222: No visible GPU is found, setting
|
|
`gpu_id` to -1
|
|
```
|
|
|
|
This is _not_ an error. This is due to the checkpoints being loaded on the
|
|
XGBoost driver, and since the driver lives on the head node (which has no
|
|
GPU), XGBoost warns that it can't use the GPU. Training still happened using
|
|
the GPUs.
