TORCH_NPU_COMPACT_ERROR_OUTPUT

功能描述

通过此环境变量可精简打印错误信息，开启后会将CANN内部调用栈、Ascend Extension for PyTorch错误码等自定义报错信息转移到plog中，仅保留有效的错误说明，提高异常信息的可读性。

• 配置为0时：正常进行ERROR打印。
• 配置为1时：启用精简ERROR打印。

此环境变量默认值为0。

配置示例

export TORCH_NPU_COMPACT_ERROR_OUTPUT=1

使用约束

无

支持的型号

• Atlas 训练系列产品
• Atlas A2 训练系列产品
• Atlas A3 训练系列产品

结果示例

• 设置为默认值0，正常进行ERROR打印时：

  >>> torch_npu.npu.set_device(100)
  ......
  RuntimeError: Initialize:build/CMakeFiles/torch_npu.dir/compiler_depend.ts:147 NPU function error: c10_npu::SetDevice(device_id_), error code is 107001

• 设置为1，开启精简打印时：

  >>> torch_npu.npu.set_device(100)
  ......
