labelimg install

過程

最初環境　python 3.6　qt5.7

*遇到了一個bug

Cannot mix incompatible Qt library (version 0x50905) with this library (version 0x50a01)

*在網上搜索之後，發現ubuntu自帶qt4,就開始換python環境了

環境 python 2.7

• 安裝pyqt4的時候出了點小問題，pip安裝沒有成功
• 解決方案：參考

conda install --channel https://conda.anaconda.org/conda-forge pyqt
conda install -c anaconda pyqt=4.11.4

• bug，保存文件的時候出錯了

TypeError: cannot serialize PyQt4.QtCore.QString(u'dog') (type QString)

• 好吧，pyqt要4.8，參考

conda install -c terradue pyqt4

• 有出錯了

 File "labelImg.py", line 26, in <module>
    from PyQt4.QtGui import *
ImportError: libQtMultimedia.so.4: cannot open shared object file: No such file or directory

結果

• 安裝

＃Python 2 + Qt4

sudo apt-get install pyqt4-dev-tools
sudo pip install lxml
make qt4py2
python2  labelImg.py

• bug

TypeError: cannot serialize PyQt4.QtCore.QString(u'dog') (type QString)

*　更改保存的代碼（個人需要的只是框的座標，保存成了txt格式）

#lib/pascal_voc_io.py
    def appendObjects(self, top):
        label = []
        for each_object in self.boxlist:
            label.append([each_object['xmin'],each_object['ymin'],each_object['xmax'],each_object['ymax']])
        return label

    def save(self, targetFile=None):
        root = self.genXML()
        labels = self.appendObjects(root)
        out_file = None
        if targetFile is None:
             print '===================================='
        else:
            myfile = targetFile.split('.')[0] +'.txt'
            print myfile
            out_file = open(myfile,'w')

        for label in labels:
            out_file.write(str(label[0])+' '+str(label[1]) + ' '+ str(label[2]) + ' ' +  str(label[3])+ '\n')
        out_file.close()
