兄弟們看看是不是這個(gè)錯(cuò)：

QObject::moveToThread: Current thread (0xe5205f0) is not the object's thread (0xa14d0f0).
Cannot move to target thread (0xe5205f0)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/xxx/python3.8/site-packages/cv2/qt/plugins" 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: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl.

VScode 80年不出個(gè)錯(cuò)，今兒冒出來這個(gè)，我也不知道是mmdet配置問題，還是opencv-python的問題，還是VScode的問題hhhh

把QT的flag打開，我們才能看到報(bào)錯(cuò)的詳細(xì)信息

export QT_DEBUG_PLUGINS=1

注意，這個(gè)執(zhí)行后，該環(huán)境變量只在當(dāng)前終端有效，關(guān)了這個(gè)終端就失效了，當(dāng)然你也可以寫到.bashrc里

然后就整出一個(gè)超級(jí)長(zhǎng)的報(bào)錯(cuò)：

與這哥們報(bào)的錯(cuò)誤差不多

這位大哥這樣做的

當(dāng)然你也可以在環(huán)境變量中添加：

export DISPLAY=:0	

launch.json 中這樣添加

解決是解決了，但是給我整出來一個(gè)

Invalid MIT-MAGIC-COOKIE-1 Key(環(huán)境變量名字)
