nvidia-dali pip安装报错

之前安装dali这个库的时候，都是按照官网的方法安装，但这几天想在新机器上安装时，一直报错

Looking in indexes: https://pypi.org/simple, https://developer.download.nvidia.com/compute/redist/
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x7f951bd14c88>: Failed to establish a new connection: [Errno -2] Name or service not known',)': /simple/nvidia-dali-cuda110/

好像是网络问题，但无论有没有kexue上网，还是无法下载安装，于是在网上找到了源码，下载到机器上，直接

pip install XXX

安装成功
