AutoRunner GPU usage

Describe the bug
AutoRunner spikes CPU usage and ends with SIGKILL9. Pytorch recognizes GPU and other scripts utilize GPU.

To Reproduce
Steps to reproduce the behavior:

1. run autorunner on HPC GPU instance
2. run data analysis
3. run algorithm generation
4. fail occurs on Step 3: Model training, validation, and inference

Expected behavior
GPU utilized and no fail on run

CPU/GPU traces from start till crash:

Start with monai/apps/auto3dseg/auto_runner.py at _train_algo_in_sequence and bundle_gen.py at _run_cmd, then inspect the generated work_dir/dints_0/scripts/search.py command from the traceback. Reproduce the Step 3 training run while monitoring CPU and GPU usage. Done means AutoRunner completes training, validation, and inference without SIGKILL and uses the available GPU.
