Tensorflow 警告 - 无法加载动态库“cupti64_101.dll”； dlerror: cupti64_101.dll 未找到

Question

我见过其他与 cupti dll 错误相关的类似问题。但是，答案似乎是dll位置需要在路径中。好吧，我的 dll 在路径中。标题中列出的警告之后是几个与 cupti dll 未加载有关的错误。

Answer 1

在此处（回答部分）提供解决方案，即使它出现在评论部分中，也是为了社区的利益。

C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\extras\CUPTI\libx64 上没有 cupti64_101.dll 文件。

由于此Could not load dynamic library 'cupti64_101.dll'; dlerror: cupti64_101.dll not found 警告在尝试运行 Tensorflow 时出现。

将cupti64_101.dll 复制到上述位置后，问题已解决。
