Debugging Environment Variables

:::{list-table} :header-rows: 1

    • Variable
    • Description
    • TORCH_SHOW_CPP_STACKTRACES
    • If set to 1, makes PyTorch print out a stack trace when it detects a C++ error.
    • TORCH_CPP_LOG_LEVEL
    • Set the log level of c10 logging facility (supports both GLOG and c10 loggers). Valid values are INFO, WARNING, ERROR, and FATAL or their numerical equivalents 0, 1, 2, and 3.
    • TORCH_LOGS
    • For a more in depth explanation of this environment variable, see {doc}/logging.
    • TORCH_DIST_NAN_CHECK
    • If set to 1, checks the input (send) buffers of every torch.distributed collective for NaNs, for any backend. Unlike TORCH_NCCL_NAN_CHECK, which is implemented natively by the NCCL backend, this is driven by the backend-agnostic ProcessGroup collective hooks.
