安装非root的cuda10.1：(失败)
sh cuda_10.1.105_418.39_linux.run提示如下错误：
Log file not open. Segmentation fault (core dumped)可能是数组越界，按照网上的方法进行尝试解决：
#设置core大小为无限 ulimit -c unlimited #设置文件大小为无限 ulimit unlimited仍然提示一样的错误！
安装非root的cuda9.2（成功）
建立conda环境：pytorch-encoding_python3.6

创建py3.7环境pytorch-encoding
pytorch1.4.0 cuda9.2
安装pytorch-encoding from source
问题：安装包名为encoding，pytorch-encoding文件夹下也有同名文件夹，导致import时到该文件夹下寻找不到就报错，而不去环境中的包中去找！
问题：使用pip install torch-encoding 安装成功之后，import encoding之后会死机，重新安装环境！
疑问：环境中已经安装名为A的包，B.py目录下也有一个名为A的文件夹，当B.py中执行：
import A解释器会到A文件夹中会搜索而不是A包中！很疑惑为什么？？？
