在另一台电脑上下载可以直接成功，这台电脑始终不行，重新下载，重新装julia都不行，可能与cuda的环境有关。。。
你能在两台电脑上分别运行一下versioninfo()给我们看看吗

您的电脑有装Nvidia的卡吗，好像是CUDA的问题
mhLeon

感谢！问题暂时解决。
问题出现在CUDA.jl在使用GPU时，需要NVIDIA的驱动以及相应的Toolkit，驱动需要在NVIDIA官网上自行下载，Toolkit可以自行下载，也可以通过artifacts自动寻找，这个报错应该是在寻找时出现问题。
解决方案：
- 本质上还是CUDA没有装好，可以通过手动自行配置CUDA的环境，包括Driver和Toolkit两部分，按照文档中提示手动下载安装后可以正常使用CUDA.jl和Flux.jl，atrifacts也不会再报错。
- 可以禁用artifacts，通过修改环境变量JULIA_CUDA_USE_BINARYBUILDER为false，这样跳过了检查，Flux.jl可以在不使用GPU的情况下可以暂时正常使用。（test依然失败）
