Jeton TX2_NX（Jetpack4.6）部署Yolo5错误整理记录qt.qpa.plugin: Could not find the Qt platform plugin “xcb“ in
tx2_nx安装的是3261的bsp,jetpack4.6,python版本3.6.9

安装过程饶了一大堆圈子，刚开始以为是QT的问题，opencv-python版本也没在意，以为是大于4.1.2就可以了。各种尝试开始了
qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.Aborted
资料贡献博主一估计也是没找到根源可以借鉴一下 这个方法，不显示界面，保存到文件夹下去打开
测试代码报错如上：以为是qt的问题
qt下程序运行问题贡献博主
nvidia论坛贡献Getting Error in Jetson Xavier -> qt.qpa.plugin: Could not find the Qt platform plugin "xcb" in "" - Jetson & Embedded Systems / Jetson Xavier NX - NVIDIA Developer Forums
按照nvidia的论坛我还安装了QT 也算获得了一个新技能
In the end what worked for me (Jetson Nano 4GB) was:
(Source: PySide2 (Qt for python) installation on Jetson Xavier 34)
-
Download Qt source:
if you need the whole Qt5 (~900MB):wget http://master.qt.io/archive/qt/5.15/5.15.2/single/qt-everywhere-src-5.15.2.tar.xz 19
or
qtbase (basic module such as QtCore, QtGui and QtWidget)(~90MB):wget http://master.qt.io/archive/qt/5.15/5.15.2/submodules/qtbase-everywhere-src-5.15.2.tar.xz 8
-
configure and install Qt5 (here I used qtbase):
tar -xpf qtbase-everywhere-src-5.15.2.tar.xz
cd qtbase-everywhere-src-5.15.2/
./configure -xcb
(must enable xcb here manually)
Choose “o” to install Qt open source version.
make -j4
sudo make install
- Now we have Qt5 under /usr/local/Qt-5.15.2
Also
#If you don't configure the installation path, you need to create a link.
sudo ln -sf /usr/local/Qt-5.15.2/bin/qmake /usr/lib/aarch64-linux-gnu/qt5/bin/qmake安装过程参考了贡献博主
贡献博主
意思是找不到xcb这个插件 ，然后去QT的安装路径下面找，我的是/usr/local/Qt-5.15.3/plugins/platforms,下面只有这几个lib，找到了libqxcb.so

nvidia@nvidia-desktop:~/yolov5-6.1$ pip in翻阅资料以后找到如下方法，无奈又回到了起点，版本还是不对 ，pip3 install opencv-python4.3到4.5都安装了一遍，安装都失败了，4.5.5将就安装上也是下面的问题，给大家伙踩个雷，不要再跳坑了。

直接使用pip3 install opencv-python和 pip3 install opencv-python--headless安装最新的4.6直接报错AttributeError: partially initialized module ‘cv2‘ has no attribute ‘_registerMatType‘ ,就应该知道
最新的opencv-python安装完不使用 --view-img:是否展示预测之后的图片/视频，默认False，也可以在本地下runs看到，应该是 opencv-python--headless的问题了
参数介绍
weights:训练的权重
source:测试数据，可以是图片/视频路径，也可以是'0'(电脑自带摄像头),也可以是rtsp等视频流
output:网络预测之后的图片/视频的保存路径
img-size:网络输入图片大小
conf-thres:置信度阈值（检测精度，作者是设置的0.25）
iou-thres:做nms的iou阈值（）
device:设置设备
view-img:是否展示预测之后的图片/视频，默认False
save-txt:是否将预测的框坐标以txt文件形式保存，默认False
classes:设置只保留某一部分类别，形如0或者0 2 3
agnostic-nms:进行nms是否也去除不同类别之间的框，默认False
augment:推理的时候进行多尺度，翻转等操作(TTA)推理
update:如果为True，则对所有模型进行strip_optimizer操作，去除pt文件中的优化器等信息，默认为False

原因就是opencv-python的版本和opencv-python-headless的版本兼容问题，安装好yolo5就不会报错了，差不多花费了我一周的时间，搭建开发环境真消耗时间,最后如下一条安装命令解决了尴尬
pip3--default-timeout=1000 install opencv-python install "opencv-python-headless<4.3" -i https://pypi.tuna.tsinghua.edu.cn/simple
