未调用 apply_async 回调函数

我是 python 的新手,我有一个函数可以计算我的数据的特征,然后返回一个应该处理并写入文件的列表。,我正在使用 Pool 进行计算,然后使用回调函数来写入文件,但是没有调用回调函数,我已经在其中放入了一些打印语句,但它肯定没有被调用。我的代码是这样的:

def write_arrow_format(results):
print("writer called")
results[1].to_csv("../data/model_data/feature-"+results[2],sep='\t',encoding='utf-8')
with open('../data/model_data/arow-'+results[2],'w') as f:
     for dic in results[0]:
         feature_list=[]
         print(dic)
         beginLine=True
         for key,value in dic.items():
              if(beginLine):
                feature_list.append(str(value))
                beginLine=False
              else:
                feature_list.append(str(key)+":"+str(value))
         feature_line=" ".join(feature_list)
         f.write(feature_line+"\n")


def generate_features(users,impressions,interactions,items,filename):
    #some processing 
    return [result1,result2,filename]





if __name__=="__main__":
   pool=mp.Pool(mp.cpu_count()-1)

   for i in range(interval):
       if i==interval:
          pool.apply_async(generate_features,(users[begin:],impressions,interactions,items,str(i)),callback=write_arrow_format)
       else:
           pool.apply_async(generate_features,(users[begin:begin+interval],impressions,interactions,items,str(i)),callback=write_arrow_format)
           begin=begin+interval
   pool.close()
   pool.join()

OpenCV调整大小更改像素值

虽然训练的PixelNet,我有TOR调整具有特定的像素值标注的图像(标签),调整前;图像像素具有特异性值(标对象),np.unique(image)[ 0 7 15] 然而,当我调整与OpenCV的形象,它适合我的网络定义像素值范围会变化

image = cv2.resize(image,(cnn_input_size, cnn_input_size),cv2.INTER_NEAREST)

np.unique(bmask)[ 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17]

这对于训练带有注释标签的图像是一个灾难,因为这些值是为其他类指定的,我想知道这是否是调整大小时OpenCV的预期行为。
