Ubuntu18.04 Pycharm下ModuleNotFoundError: No module named 'deeplab'

1.根据https://www.cnblogs.com/zmbreathing/p/deeplab_v3plus.html在终端中成功运行deeplab的test文件后，在pycharm中出现问题：

/home/mingzhou/anaconda3/bin/python3 /home/mingzhou/PycharmProjects/deeplab_model_test/deeplab_model_test.py
Traceback (most recent call last):
File "/home/mingzhou/PycharmProjects/deeplab_model_test/deeplab_model_test.py", line 20, in <module>
from deeplab import common
ModuleNotFoundError: No module named 'deeplab'

2.根据https://blog.csdn.net/pipisorry/article/details/39909057#t9的方法一在～/.profile中设置环境变量，无效

但在pycharm的环境变量中已经有了PYTHONPATH=/home/user/models/research/:/home/user/models/research/slim

又发现如果使用bash pycharm.sh启动才有上述PYTHONPATH，如果直接启动则没有

第二天直接打开pycharm也有上述PYTHONPATH，但在user的bashrc和profile均修改了PYTHONPATH，此处还是不变

最后发现：

用快捷方式(sh方式)启动pycharm时，无论是修改~/.bashrc中还是~/.profile中的环境变量，pycharm中显示的系统环境变量都不变
但将电脑重新启动后，pycharm中显示的系统环境变量就会变为~/.profile中的环境变量

用bash方式启动pycharm时，pycharm中显示的系统环境变量变为~/.bashrc中的环境变量(需要重进终端)

3.发现conda没有安装jupyter、matplotlib、PrettyTable

输入conda install jupyter

conda install matplotlib

conda install PrettyTable

安装PrettyTable时出现错误

根据https://blog.csdn.net/ewba_gis_rs_er/article/details/84671406成功解决此问题

anaconda search -t conda PrettyTable

anaconda show lightsource2-tag/prettytable

conda install --channel https://conda.anaconda.org/lightsource2-tag prettytable

但还是没有解决No module问题

4.按照官方文档https://github.com/tensorflow/models/blob/master/research/deeplab/g3doc/installation.md将PYTHONPATH设为以下，即在~/.profile末尾添加

export PYTHONPATH=$PYTHONPATH:/home/user/models/research:/home/user/models/research/slim

 出现以下错误

若按https://www.cnblogs.com/zmbreathing/p/deeplab_v3plus.html第5点将PYTHONPATH设为

export PYTHONPATH=$PYTHONPATH=/home/user/models/research:/home/user/models/research/slim

会再次出现No module named 'deeplab'问题

5.见https://www.cnblogs.com/zmbreathing/p/pycharm_cannot_import_monitoring_deeplab.html解决4中

ImportError:cannot import name 'monitoring'问题
