0. 如何查看自己labelme安装的位置
   例如通过pip3.8安装

pip3.8 install labelme

可以通过查看pip3.8版本寻找对应的python安装位置

pip3.8 -V

然后就可以在对应版本的python下修改相应的文件

1. delete 删除标签时，不再弹出对话框

   找到./python/site-packages/labelme/app.py

def deleteSelectedShape(self):
        self.remLabels(self.canvas.deleteSelected())
        self.setDirty()
        if self.noShapes():
            for action in self.actions.onShapesPresent:
                action.setEnabled(False)
        #yes, no = QtWidgets.QMessageBox.Yes, QtWidgets.QMessageBox.No
        #msg = self.tr(
        #    "You are about to permanently delete {} polygons, "
        #    "proceed anyway?"
        #).format(len(self.canvas.selectedShapes))
        #if yes == QtWidgets.QMessageBox.warning(
        #    self, self.tr("Attention"), msg, yes | no, yes
        #):
            #self.remLabels(self.canvas.deleteSelected())
            #self.setDirty()
            #if self.noShapes():
            #    for action in self.actions.onShapesPresent:
            #        action.setEnabled(False)

2. 选择其他图像，自动保存当前标签信息，不再弹出对话框
   找到./python/site-packages/labelme/app.py

def mayContinue(self):
        if not self.dirty:
            return True
        self.saveFile()
        return True
        #mb = QtWidgets.QMessageBox
        #msg = self.tr('Save annotations to "{}" before closing?').format(
        #    self.filename
        #)
        #answer = mb.question(
        #    self,
        #    self.tr("Save annotations?"),
        #    msg,
        #    mb.Save | mb.Discard | mb.Cancel,
        #    mb.Save,
        #)
        #if answer == mb.Discard:
        #    return True
        #elif answer == mb.Save:
        #    self.saveFile()
        #    return True
        #else:  # answer == mb.Cancel
        #    return False

3. imageData 不再存储 image的信息，减少json存储大小
   找到./python/site-packages/labelme/label_file.py
   imageData=imageData 改为 imageData=None

def save(
        self,
        filename,
        shapes,
        imagePath,
        imageHeight,
        imageWidth,
        imageData=None,
        otherData=None,
        flags=None,
    ):
        if imageData is not None:
            imageData = base64.b64encode(imageData).decode("utf-8")
            imageHeight, imageWidth = self._check_image_height_and_width(
                imageData, imageHeight, imageWidth
            )
        if otherData is None:
            otherData = {}
        if flags is None:
            flags = {}
        data = dict(
            version=__version__,
            flags=flags,
            shapes=shapes,
            imagePath=imagePath,
            # imageData=imageData,
            imageData=None,
            imageHeight=imageHeight,
            imageWidth=imageWidth,
        )
        for key, value in otherData.items():
            assert key not in data
            data[key] = value
        try:
            with open(filename, "w") as f:
                json.dump(data, f, ensure_ascii=False, indent=2)
            self.filename = filename
        except Exception as e:
            raise LabelFileError(e)

4. image list 列表按照资源管理器进行排序，顺序显示图像
   找到./python/site-packages/labelme/app.py
   首先 import natsort，如果没有安装，可以pip install natsort安装

def scanAllImages(self, folderPath):
        extensions = [
            ".%s" % fmt.data().decode().lower()
            for fmt in QtGui.QImageReader.supportedImageFormats()
        ]

        images = []
        for root, dirs, files in os.walk(folderPath):
           for file in files:
               if file.lower().endswith(tuple(extensions)):
                   relativePath = osp.join(root, file)
                   images.append(relativePath)
        # images.sort(key=lambda x: x.lower())
        images = natsort.natsorted(images)
        return images
