如何查看自己labelme安裝的位置
例如通過pip3.8安裝

pip3.8 install labelme

可以通過查看pip3.8版本尋找對應的python安裝位置

pip3.8 -V

然后就可以在對應版本的python下修改相應的文件

delete 刪除標簽時，不再彈出對話框

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)

選擇其他圖像，自動保存當前標簽信息，不再彈出對話框
找到./python/site-packages/labelme/app.py

def mayContinue(self):if not self.dirty:return Trueself.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

imageData 不再存儲 image的信息，減少json存儲大小
找到./python/site-packages/labelme/label_file.py
imageData=imageData 改為 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 datadata[key] = valuetry:with open(filename, "w") as f:json.dump(data, f, ensure_ascii=False, indent=2)self.filename = filenameexcept Exception as e:raise LabelFileError(e)

image list 列表按照資源管理器進行排序，順序顯示圖像
找到./python/site-packages/labelme/app.py
首先 import natsort，如果沒有安裝，可以pip install natsort安裝

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
