RecursionError:我在寻找一种减少循环次数的方法

Question

我正在寻找一个优化我的代码，以避免以下错误，并使我的程序更快。maximum recursion depth exceeded while calling a Python object

我想在一个码头容器中执行这段代码。在我的机器上，它在本地工作得很好。

我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，但我认为这不是一个优化的方法，而且非常慢。

编辑:这是堆栈跟踪

非常感谢你的帮助。

它似乎是固定，但是没有用这个补丁构建的pypi封装。

此bug的起源描述如下：

Python3.8从int和object.repr().中移除str()，现在调用对象。 DSfloat.str()，DSfloat.repr()和IS.repr()都调用父类str()，后者调用子类‘repr()方法等等，这将导致递归错误。 这一公共关系： 修复DSfloat.__str__()，方法是创建一个调用repr()，删除“mark. DSfloat.__repr__()”，方法是调用父类的__repr__()，而不是str()，方法是以类似于DSfloat.__str__()的方式实现IS.__str__()，并使IS.__repr__()与 DSfloat.repr()

您可以尝试直接从git安装它：

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