Ubuntu16.04 conda环境运行FaiMOT及相关配置

前几天下载FairMOT项目 也配置好相关环境 今天想准备跑一下代码 看看效果如何
结果运行代码发现 一下问题
再跑kitti数据前，准备先测试一下项目提供的demo视频
按照项目给的demo要求走

(FairMOT) ckq@ckq:~/git/FairMOT/src$ python demo.py mot --load_model ../models/all_dla34.pth --conf_thres 0.4
Traceback (most recent call last):
  File "demo.py", line 11, in <module>
    from tracking_utils.utils import mkdir_if_missing
  File "/home/ckq/git/FairMOT/src/lib/tracking_utils/utils.py", line 6, in <module>
    import cv2
ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type

然后在conda 环境下

(FairMOT) ckq@ckq:~/git/FairMOT/src$ python
Python 3.7.6 | packaged by conda-forge | (default, Jun  1 2020, 18:57:50) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
  File "", line 1, in <module>
ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type
>>> 
 发现 conda 环境没有 cv2模块

但在原本系统下我已经装了 opencv

  ckq@ckq:~$ python
Python 2.7.12 (default, Apr 15 2020, 17:07:12) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2

发现没问题
看来是conda环境下的opencv2有问题

开始网上查找相关解决问题
打开bashrc文件

 sudo gedit ~/.bashrc

在文末加入：

 #运行ROS时需要注释掉这行代码，运行非ROS时需要加上这行代码
export PYTHONPATH="/home/ckq/anaconda3/lib/python3.7/site-packages:$PYTHONPATH"

保存

source ~/.bashrc

但是 保存之后再在conda 环境下：

(FairMOT) ckq@ckq:~$ python
Python 3.7.6 | packaged by conda-forge | (default, Jun  1 2020, 18:57:50) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Traceback (most recent call last):
  File "", line 1, in <module>
ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type

发现这并没有 解决根本问题
只是 在项目代码中 换了另一个报错问题

查看了这里的第一种办法 ，但是有个问题需要注意一下 就是运行ros的需要注释掉改行代码，运行非ros是需要加上这行代码
第二种方法没尝试过 不知道这样子是否会把系统的ros搞崩掉 所以没有尝试 so还是用蠢办法吧

https://blog.csdn.net/qq_34544129/article/details/81946494

下面这个链接也是同样解决方法 他也在conda环境下：
https://www.cnblogs.com/gdut-gordon/p/9480652.html

最后 我还是选择了第二个方法

进入conda的环境：
输入python

 >>> import cv2
Traceback (most recent call last):
  File "", line 1, in <module>
ImportError: /opt/ros/kinetic/lib/python2.7/dist-packages/cv2.so: undefined symbol: PyCObject_Type
 >>> import sys
>>> sys.path.remove('/opt/ros/kinetic/lib/python2.7/dist-packages')
>>> import cv2
 Traceback (most recent call last):
  File "", line 1, in <module>
ModuleNotFoundError: No module named 'cv2'
输入：
 pip install opencv-python
 
 下载超时！！！！
 ERROR: Exception:
 pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

换用国内原

 pip install https://pypi.tuna.tsinghua.edu.cn/simple

继续报错

 pip install -i https://pypi.tuna.tsinghua.edu.cn/simple --trusted-host pypi.tuna.tsinghua.edu.cn opencv-python

之前方法 我是把remove运行在conda python 环境下，每次运行完，进入项目，还是报同样的错位，有问题！！！
后来得知 要把这话放在报错文件夹下面

import sys
sys.path.remove('/opt/ros/kinetic/lib/python2.7/dist-packages')

添加在报错的文件夹下面！！！！

OK！！！
解决这个问题 成功了一半 下面报的错都是我没有下载一下库而已！！！

之后这个问题解决

出现新的报错：

总之一路报错，路改！！！！
ok！！！
到这里成功运行demo！！！

贴图贴图！！！

自己也录制了小视频！！！效果不是很好 可能因为我是室内环境吧！！！
