labelme在Anaconda安装中出现的问题及解决方案

labelme在Ubuntu中Anaconda安装中出现的一些问题解决方案

安装labelme过程：

conda create --name=labelme python=3
conda activate labelme
pip install labelme

问题一：报错Aborted (core dumped)

问题描述：

[INFO ] init:get_config:70 - Loading config file from: /home/XXX/.labelmerc
Traceback (most recent call last):
File “/home/XXX/fxp/envs/labelme/lib/python3.10/site-packages/labelme/widgets/canvas.py”, line 618, in paintEvent
p.translate(self.offsetToCenter())
File “/home/XXX/fxp/envs/labelme/lib/python3.10/site-packages/labelme/widgets/canvas.py”, line 659, in offsetToCenter
return QtCore.QPoint(x, y)
TypeError: arguments did not match any overloaded call:
QPoint(): too many arguments
QPoint(int, int): argument 1 has unexpected type ‘float’
QPoint(QPoint): argument 1 has unexpected type ‘float’
Aborted (core dumped)

解决方案：更换python版本

conda env remove -n labelme
conda create --name=labelme python=3.9
conda activate labelme
pip install labelme

问题二：上一步安装完后又出现了× Encountered error while trying to install package的问题

问题描述：

note: This error originates from a subprocess, and is likely not a problem with
pip.
error: legacy-install-failure

× Encountered error while trying to install package.
╰─> matplotlib

note: This is an issue with the package mentioned above, not pip.
hint: See above for output from the failure.

解决方案：安装对应依赖

sudo apt-get update
sudo apt-get install libfreetype6-dev
sudo apt-get install pkg-config
sudo apt-get install libpng-dev
sudo apt-get install pkg-config

两步下来最终能够在ubuntu20.04的Anaconda中成功安装labelme！
