【中文标题】PyQt5 在导入 skimage 时出现问题

【英文标题】：PyQt5 has issue while importing in skimage

【发布时间】：2017-12-04 19:36:39

【问题描述】：

我正在使用 Skimage 处理 RGB 颜色处理的图像，并具有以下软件包配置：

Python 3.6.1

scikit-image 0.13.0

pyqt 5.6.0

from skimage import io

import sip
sip.setapi('QString', 2)
from PyQt5 import QtGui

io.use_plugin('pil','imread')

img=io.imread('RpMkYUX.jpg')
io.use_plugin('qt' ,'imshow')
io.imshow(img)
io.show()

期望输出为图像

预期输出

我得到以下错误：

(C:\Users\rahul\Anaconda3) C:\Users\rahul\AnacondaProjects\15_PIL>python 2_.py
Traceback (most recent call last):
  File "C:\Users\rahul\Anaconda3\lib\site-packages\skimage\io\_plugins\qt_plugin.py", line 11, in <module>
    from PyQt4.QtGui import (QApplication, QImage,
ModuleNotFoundError: No module named 'PyQt4'

During handling of the above exception, another exception occurred:

【问题讨论】：

我看到 skimage 需要 PyQt4，而不是你安装了 PyQt5：pyqt 5.6.0，一个可能的解决方案是安装 PyQt4。阅读：***.com/questions/21637922/…

我添加了一个问题来解决这个问题：github.com/scikit-image/scikit-image/issues/2912

【参考方案1】：

我使用 pip 19.1.1 和 Python 3.7.4

D:\tesF> python scikit-image-tes.py
Traceback (most recent call last):
  File "scikit-image-tes.py", line 10, in <module>
    io.use_plugin('qt' ,'imshow')
  File "C:\Users\pcname\AppData\Roaming\Python\Python37\site-packages\skimage\io\manage_plugins.py", line 254, in use_plugin
    _load(name)
  File "C:\Users\pcname\AppData\Roaming\Python\Python37\site-packages\skimage\io\manage_plugins.py", line 298, in _load
    fromlist=[modname])
  File "C:\Users\pcname\AppData\Roaming\Python\Python37\site-packages\skimage\io\_plugins\qt_plugin.py", line 5, in <module>
    from qtpy.QtWidgets import (QApplication, QLabel, QMainWindow, QWidget,
ModuleNotFoundError: No module named 'qtpy'

在我出错之前

解决者：

D:\tesF> pip install sip
D:\tesF> pip install qtpy

在此之前，我已经安装了

D:\tesF> pip install PyQt5
