环境信息 #

Python Version: 3.9.13
CUDA Installed: Yes
cuDNN Installed: Yes
GPU: RTX 4070
IDE: PyCharm

已尝试的步骤 #

• 确认CUDA和cuDNN安装无误
• 检查TensorFlow版本与GPU架构的兼容性
• 验证Python版本与TensorFlow的兼容性

解决方案 #

核心原因 #

TensorFlow从2.10版本开始，已经不再单独提供tensorflow-gpu包，官方将CPU和GPU版本合并为同一个tensorflow包。你安装的tensorflow-gpu==2.12.0是过时的遗留包，其依赖声明语法不符合新版setuptools的解析规则，导致元数据生成失败。

具体操作步骤 #

1. 清理旧包（如果有残留）
   执行命令卸载可能存在的tensorflow-gpu：

   pip uninstall tensorflow-gpu -y
   

2. 安装官方统一版TensorFlow
   根据你的Python3.9和RTX4070（支持CUDA 11.8或12.x），推荐安装TensorFlow 2.15.0（长期支持版）或2.16.0：

   pip install tensorflow==2.15.0
   

3. 验证GPU是否可用
   在Python环境中运行以下代码，确认TensorFlow是否成功调用GPU：

   import tensorflow as tf
   print(tf.config.list_physical_devices('GPU'))
   

   如果输出包含你的RTX4070设备信息，说明安装成功。
