Tensorflow 警告 - 无法加载动态库“cupti64_101.dll"；dlerror: 找不到 cupti64_101.dll [英] Tensorflow Warning - Could not load dynamic library 'cupti64_101.dll'; dlerror: cupti64_101.dll not found

问题描述

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未加载 cupti dll 的事实相关的错误.

I've seen other similar issues related to cupti dll error. However, the answer seems to be that the dll location needs to be in the path. Well, my dll is in the path. The warning listed in the title is followed by several errors related to the fact that the cupti dll was not loaded.

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

由于这个无法加载动态库'cupti64_101.dll'；dlerror: cupti64_101.dll not found 在尝试运行 Tensorflow 时出现警告.

Due to this Could not load dynamic library 'cupti64_101.dll'; dlerror: cupti64_101.dll not found warning has appeared when ever trying to run Tensorflow.

一旦将 cupti64_101.dll 复制到上述位置，问题就解决了.

Once cupti64_101.dll copied to the above location, issue has resolved.
