   1）PaddlePaddle版本：paddle1.8.4    2）CPU：请提供CPU型号，MKL/OpenBlas/MKLDNN/等数学库的使用情况    3）GPU：RTX2070 CUDA=9.0 CUDNN=7.3.1 (cuda、cudnn安装在conda上)    4）系统环境：ubuntu19.10 python=3.7.7

• 安装方式信息： 1）conda
• 问题描述：按照官方安装教程，使用conda安装paddle,运行时出现 >>> import paddle.fluid Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/__init__.py", line 37, in <module> import paddle.complex File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/complex/__init__.py", line 15, in <module> from . import tensor File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/complex/tensor/__init__.py", line 15, in <module> from . import math File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/complex/tensor/math.py", line 15, in <module> from paddle.common_ops_import import * File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/common_ops_import.py", line 15, in <module> from paddle.fluid.layer_helper import LayerHelper File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/fluid/__init__.py", line 35, in <module> from . import framework File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/fluid/framework.py", line 35, in <module> from . import core File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/fluid/core.py", line 226, in <module> if platform.system().lower() == 'linux' and less_than_ver(get_glibc_ver(), File "/home/tipray/Software/anaconda3/envs/paddle/lib/python3.7/site-packages/paddle/fluid/core.py", line 204, in get_glibc_ver return run_shell_command("ldd --version | awk '/ldd/{print $NF}'").strip() AttributeError: 'NoneType' object has no attribute 'strip' 并且在Pycharm打开paddle的项目，同样会出现这个问题 系统环境变量已经设置conda 的paddle环境变量 /home/tipray/Software/anaconda3/envs/paddle/bin:/home/tipray/Software/anaconda3/condabin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/usr/local/cuda-9.0/bin
