我正在尝试访问 DICOM 文件 [以医学数字成像和通信 (DICOM) 格式保存的图像]：
import dvc.api
path = 'dir/image.dcm'
remote = 'remote_name'
repo = 'git_repo'
mode = 'r'
data = dvc.api.read(path = path, remote = remote, repo = repo, mode = mode)
当我运行前面的代码时，在“下载进度条”完成后，我收到以下错误：
Traceback (most recent call last): File "draft.py", line 7, in <module> mode ='r') File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\site-packages\dvc\api.py", line 91, in read return fd.read() File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\encodings\cp1252.py", line 23, in decode return codecs.charmap_decode(input,self.errors,decoding_table)[0] UnicodeDecodeError: 'charmap' codec can't decode byte 0x81 in position 764: character maps to <undefined>
我试图通过使用 encoding 参数来解决这个问题：
data = dvc.api.read(path = path, remote = remote, repo = repo, mode = mode, encoding='ANSI')
因为，当我使用例如 Notepad++ 打开一个 DICOM 文件时，这是指定的编码。但是，它会引发错误：
Exception ignored in: <bound method Pool.__del__ of <dvc.fs.pool.Pool object at 0x0000021D1347A160>> Traceback (most recent call last): File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\site-packages\dvc\fs\pool.py", line 42, in __del__ File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\site-packages\dvc\fs\pool.py", line 46, in close File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\site-packages\dvc\fs\ssh\connection.py", line 71, in close File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\site-packages\paramiko\sftp_client.py", line 194, in close File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\site-packages\paramiko\sftp_client.py", line 185, in _log File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\site-packages\paramiko\sftp.py", line 158, in _log File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\logging\__init__.py", line 1372, in log File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\logging\__init__.py", line 1441, in _log File "C:\Users\lbrandao\anaconda3\envs\my_env\lib\logging\__init__.py", line 1411, in makeRecord TypeError: 'NoneType' object is not callable
我也试过encoding = 'utf-8'了，但“UnicodeDecodeError”继续出现：
Traceback (most recent call last): File "draft.py", line 7, in <module> mode ='r', encoding='utf-8') File "C:\Users\lbrandao\anaconda3\envs\ccab_env_dev\lib\site-packages\dvc\api.py", line 91, in read return fd.read() File "C:\Users\lbrandao\anaconda3\envs\ccab_env_dev\lib\codecs.py", line 321, in decode (result, consumed) = self._buffer_decode(data, self.errors, final) UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd0 in position 140: invalid continuation byte
有人可以帮忙吗？谢谢。
