フォルダ内にイメージが見つからない場合、プログラムがクラッシュしますが、ログ記録の問題に記録する必要があります。

Question

イメージフォルダ内に特定のイメージが見つからない場合、プログラムがクラッシュします。 imagenameがimagecolumnに存在するが、フォルダ内に見つからない場合は、クラッシュします。イメージファイルをログに記録しようとしましたが失敗しました。トレースバックが

import pandas as pd

class Image:

     # console handler 
     console = logging.StreamHandler() 
     console.setLevel(logging.ERROR) 
     logging.getLogger("").addHandler(console) 


     # using panda to open and read csv 
     df = pd.read_csv('rgw.csv') 
     df['Image'] = df.ImageName + "_" + df.ImageWChain + ".jpg"

       logger.debug(" <- This image was not found in the folder") 


if __name__=="__main__": 
    obj = Image() 
    obj.image_fix() 

きている。

 #checks whether image file exits in folder or not 
     if (os.path.isfile(oldFileName)): 

あなたはoldFileNameの存在をテストしたが、その後コピーしようとしているold_image ：

  #creates duplicate copy of an image 
      for old_image, new_image in zip(df.ImageName,df.Image): 
       shutil.copy2(old_image,new_image)
