关于环境配置的问题：sh compile_op.sh

[YAOmmeng]

胡博士你好，我最近也在跑您的神经网络，但是在进行环境配置sh compile_op.sh的时候，出现了下面的问题：

我理解的这一步是通过Cython将knn.pyx 编译为 knn.cpp，但是出现了上述的警告，之后在utils/nearest_neighbors/lib/python/下找不到nearest_neighbors这个文件。请问是我环境配置的有问题吗还是其他的什么，我也是按照您之前的环境去配置的，还请您解答

我已经解决了，解决方法是换了一台服务器，重装系统之后重新配置驱动和环境。感谢您提供的代码。

@zeng-ziyin 我想请教你一下，你跑的RandLA-Net算法是严格按照作者所提供的驱动版本来的吗，可不可以用更高的版本呢

[RaywoodWEt]

可能是目录有问题，编译的时候改成绝对路径试试

@RaywoodWEt

可能是目录有问题，编译的时候改成绝对路径试试

您好，麻烦您能具体说一下怎么改路径么，我尝了一下都不太好用，一直提示

[guan2000910]

您好，请问这个问题如何解决的？
