labelme的安装

首先尝试在(openmmlab)的python3.8的环境下安装（失败）。应该是我环境其他部分不对，和python版本应该没什么关系。（后续，创建新的环境后成功，可直接看最后一部分。）

首先安装是没问题的

pip install labelme 

输入labelme运行时报错：

错误1：

ImportError: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /home/lb/anaconda3/envs/openmmlab/lib/python3.8/site-packages/scipy/linalg/_matfuncs_sqrtm_triu.cpython-38-x86_64-linux-gnu.so)

?解决报错1：

查看：

strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

发现确实没有，查看 当前环境下（openmmlab）的lib，发现有GLIBCXX_3.4.26

strings /home/lb/anaconda3/envs/openmmlab/lib/libstdc++.so.6 | grep GLIBCXX

于是先做好备份：

备份到桌面

sudo cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /home/lb/desktop

然后删除

sudo rm /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /home/lb/desktop

最后复制

sudo cp /home/lb/anaconda3/envs/openmmlab/lib/libstdc++.so.6  /usr/lib/x86_64-linux-gnu/

报错1解决。

错误2：

解决错误2：

qt版本太高引起的

pip install pyqt5==5.14.0

错误3：

Traceback (most recent call last):
? File "/home/lb/anaconda3/envs/openmmlab/bin/labelme", line 5, in <module>
??? from labelme.__main__ import main
? File "/home/lb/anaconda3/envs/openmmlab/lib/python3.8/site-packages/labelme/__init__.py", line 6, in <module>

??? raise QtBindingsNotFoundError from None
qtpy.QtBindingsNotFoundError: No Qt bindings could be found

未解决

找了一会问题，没找到问题所在！咱头也不铁，重新创建环境，以前的电脑是python3.7可以运行，这次直接安装3.7的环境。

开始安装

conda create -n labelme python=3.7

conda activate labelme

conda install pyqt

pip install labelme

报错

? File "/home/lb/anaconda3/envs/labelme/lib/python3.7/site-packages/pip/_vendor/urllib3/response.py", line 443, in _error_catcher
??? raise ReadTimeoutError(self._pool, None, "Read timed out.")
pip._vendor.urllib3.exceptions.ReadTimeoutError: HTTPSConnectionPool(host='files.pythonhosted.org', port=443): Read timed out.

显然是超时了

解决方法：

换个源pip

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

安装成功！

终端输入

labelme 

可以开始标注了！?
