Python cv2.imshow() 因 Abort 陷阱崩溃：6

Question

我的代码：

import cv2
print(cv2.__version__)
img = cv2.imread("img.jpg")
print(len(img))
print("now showing")
cv2.imshow("img",img)
cv2.waitkey(0)

我也试过waitkey(1)但错误似乎发生在cv2.imshow行（第 6 行）

错误跟踪：

objc[73658]: Class RunLoopModeTracker is implemented in both /Users/j/opt/anaconda3/lib/python3.7/site-packages/cv2/.dylibs/QtCore (0x110aca7f0) and /Users/j/opt/anaconda3/lib/libQt5Core.5.9.7.dylib (0x128e18a80). One of the two will be used. Which one is undefined.
QObject::moveToThread: Current thread (0x7f80b2434fa0) is not the object's thread (0x7f80b244ec40).
Cannot move to target thread (0x7f80b2434fa0)

You might be loading two sets of Qt binaries into the same process. Check that all plugins are compiled against the right Qt binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of binaries are being loaded.
qt.qpa.plugin: Could not load the Qt platform plugin "cocoa" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: cocoa, minimal, offscreen.

Abort trap: 6
