结果如下，我运行项目stylegan2，但是失败。所以我需要帮助。链接是https://github.com/NVlabs/stylegan2

我需要帮助。
我遇到了相同的错误。一个讨厌的解决方法是将标志--std=c++11和-DNDEBUG添加到nvcc中的dnnlib/tflib/custom_ops.py ln 64调用中：
cmd = 'nvcc --std=c++11 -DNDEBUG ' + opts.strip()
为什么同时使用--std和-DNDEBUG？
--std=c++11给了我以下错误：
RuntimeError：NVCC返回了错误。请参阅下面的完整命令行并输出日志：

1编译中检测到错误“ /tmp/tmp8nryqyhs/fused_bias_act.cpp1.ii”。
通过使用标志-DNDEBUG，as explained in this git thread来阻止。
该解决方案很丑陋，对于作者来说，通过提供更多输入选项或其他方式（或说明如何执行此操作）来解决此问题将是很酷的。但是目前，它可以。
