| :::tip 提示 | ||
| **环境依赖**: 使用 Python UDF 前，必须在所有 BE 节点的 Python 环境中预先安装 **`pandas`** 和 **`pyarrow`** 两个库，这是 Doris Python UDF 功能的强制依赖。详见 [Python UDF 环境配置](python-user-defined-function#python-udfudafudtf-环境配置与多版本管理)。 | ||
|
|
||
| **日志路径**: Python UDF Server 的运行日志位于 `output/be/lib/udf/python/python_udf_output.log`。用户可以在该日志中查看 Python Server 的运行情况、函数执行信息和调试错误。 |

| **解决方案**: | ||
| 1. 检查所有节点的 Python 版本和依赖版本 | ||
| 2. 统一使用 `requirements.txt` 或 `environment.yml` 部署环境 |
