一、错误描述

安装 CUDA 后，在 Visual Studio Code 中使用 jupyter notebook，无论是使用 TensorFlow 或者 PyTorch，涉及 Model 相关的代码时，会报错：

info 10:44:12.758: kill daemon
error 10:44:12.758: Raw kernel process exited code: 3221226505

}

（一）提醒

翻看 log 中 error 的前文，CUDA 和 cuDNN 是可以被调起的。

仔细看 error 中的内容，似乎错误出在 jupyter 上，但其实不然。

error 10:44:12.768: Error in waiting for cell to complete [Error: Canceled future for execute_request message before replies were doneat t.KernelShellFutureHandler.dispose (c:\Users\Eddie\.vscode\extensions\ms-toolsai.jupyter-2022.6.1201981810\out\extension.node.js:2:32353)at c:\Users\Eddie\.vscode\extensions\ms-toolsai.jupyter-2022.6.1201981810\out\extension.node.js:2:51405

二、解决方法

（一）使用浏览器运行 jupyter 查看错误（建议跳过）

此步骤建议跳过！在此解释只为记录完整的错误解决步骤。

使用命令安装 jupyter，

pip install jupyter

在浏览器中打开 .ipynb 文件，重新运行，出现与在 Visual Studio Code 中不一样的错误：

Could not locate zlibwapi.dll

（二）安装 Zlib

参照 NVIDIA CUDNN DOCUMENTATION 安装 Zlib，问题解决！

三、参考

Could not locate zlibwapi.dll. Please make sure it is in your library path
tensorflow出现报错： Could not locate zlibwapi.dll或者Could not load library cudnn_cnn_infer64_8.dll.
