在另一臺電腦上使用caffe python版本，顯示

???????? Backend Qt5Agg is interactive backend. Turning interactive mode on.
???????? Failed to enable GUI event loop integration for 'qt5'

???????? ...................

???????? PyQt4 failed...

原因，沒有安裝PyQt4，而使用了PyQt5。

下載個PyQt4文件，安裝完成。

出現(xiàn)：

環(huán)境優(yōu)先使用了PyQt5。

1.進(jìn)入 C:\Works\Anaconda2\Lib\site-packages 目錄，刪除PyQt5；

導(dǎo)入成功；

但是在使用時候仍然判定API為PyQt5，使用失敗。

2.卸載Matplotlib????????? pip uninstall Matplotlib

3.重裝Matplotlib????????? pip install Matplotlib

使用成功。
