python - RecursionError:我正在寻找一种减少循环次数的方法

我正在寻找代码优化方案，以避免出现以下错误并使程序运行更快。
maximum recursion depth exceeded while calling a Python object

我正在寻找在docker容器中执行此代码。它在我的机器上本地完美运行。

我正在寻找一种减少循环次数的方法。

def reidentify(self):
        try:
            # Check if file is re-identify
            self.check_if_dicom_is_reidentify()

            LOGGER.info(f"Anonymization in progress for {self.dirpath_output}")

            # Get patient data
            json_data = json.loads(self.get_patient_data().decode('utf-8'))

            # Re-identification
            archive = zipfile.ZipFile(self.download.dirpath_download, 'r')

            for file in archive.namelist():

                # Check if the file is a dicom
                if not file.endswith('.dcm'):
                    continue

                # Reading dicom file
                dicom_data = io.BytesIO(archive.read(file))
                ds = pydicom.dcmread(dicom_data)

                # Edit Dicom general fields
                for key in json_data['tags']:
                    ds.data_element(key).value = json_data['tags'][key]

                # Edit Dicom series field
                for key in json_data['series']:
                    if key['obfuscated_uid'] != ds.data_element('SeriesInstanceUID').value:
                        continue

                    for tag in key['tags']:
                        ds.data_element(tag).value = key['tags'][tag]

                # Save re-identify dicom
                ds.save_as(f'{self.dirpath_tmp}/{os.path.basename(file)}')

        except Exception as e:
            LOGGER.error(e)

这段代码给出了预期的结果，但是我认为它不是一种优化的方法，而且非常慢。

编辑：这是堆栈跟踪

非常感谢您的帮助。

最佳答案

似乎是fixed，但没有使用该修复程序构建的pypi package。

此错误的来源描述如下：


  Python 3.8从int和float删除str（），现在调用
  object.str（）本身默认为object.repr（）。
  
  DSfloat.str（），DSfloat.repr（）和IS.repr（）都调用
  父类的str（）调用子类的repr（）方法
  等等，这会导致递归错误。
  
  该PR：

Fixes DSfloat.__str__() by creating a calling repr() instead and removing the " marks.
Fixes DSfloat.__repr__() by calling the parent class' __repr__() instead of str()
Fixes IS.__repr__() by implementing IS.__str__() in a similar manner to DSfloat.__str__() and making IS.__repr__() symmetric with

  
  DSfloat.repr（）




您可以尝试直接从git repo安装它：

pip uninstall pydicom
pip install git+https://github.com/pydicom/pydicom.git
