compiler-errors - OpenCL编译器对Windows 10用户配置文件敏感吗？

Question

长话短说，我在使用OpenCL库的Windows 10上使用darktable。暗表在后台将使用OpenCL编译器来编译内核(更多细节是https://github.com/darktable-org/darktable/issues/3717)。不幸的是我遇到了错误

但是，当我使用另一个用户配置文件/帐户登录同一台计算机时，它就可以正常工作。因此，这一定是环境问题。我没有OpenCL的经验，所以我想了解一下如何“清理”我的配置文件来修复OpenCL编译器？

Answer 1

这不是环境问题，而是缓存问题。

Darktable缓存会编译OpenCL内核，然后在下一次尝试加载它们时加快速度。不幸的是，由于某种原因，您拥有的缓存对于您的设备而言是不正确的(也许您更新了系统/驱动程序/某些内容，而blacktable错过了它)。您需要清除Darktable内核缓存。从日志看来，它在以下目录中:

C:\Users\Hardy\AppData\Local\Microsoft\Windows\INetCache\darktable\cached_kernels_for_Ellesmere

只需转到那里并删除所有内容即可。
