将python2 PIL转换为python3代码
问题描述:
我试图从python2转换为python3的程序使用PIL
python图像库。将python2 PIL转换为python3代码
我尝试从网上下载缩略图以在tkinter样式gui中显示。这是,我认为,问题的代码行:
# grab the thumbnail jpg.
req = requests.get(video.thumb)
photo = ImageTk.PhotoImage(Image.open(StringIO(req.content)))
# now this is in PhotoImage format can be displayed by Tk.
plabel = tk.Label(tf, image=photo)
plabel.image = photo
plabel.grid(row=0, column=2)
程序停止,并给出了类型错误,这里是backtrce:
Traceback (most recent call last): File "/home/kreator/.local/bin/url-launcher.py", line 281, in <module>
main()
File "/home/kreator/.local/bin/url-launcher.py", line 251, in main
runYoutubeDownloader()
File "/home/kreator/.local/bin/url-launcher.py", line 210, in runYoutubeDownloader
photo = ImageTk.PhotoImage(Image.open(StringIO(req.content)))
TypeError: initial_value must be str or None, not bytes
我如何满足这里python3的要求是什么?
答
在这种情况下,您可以看到您导入的库不支持Python3。这不是你可以在自己的代码中修复的东西。
缺乏Python3支持是因为PIL已经停用了相当长一段时间了。有一个叉积极维护,我会建议您使用,而不是:https://pillow.readthedocs.io/
您可以从pypi下载它。
