使用pickle.load时报错could not find MARK

这个错误通常是由于使用错误的pickle版本导致的。请确保你在使用pickle.load()之前和之后都使用相同版本的pickle。

如果你正在使用Python 3.x，那么你需要使用"rb"模式打开pickle文件，以二进制模式读取文件内容。例如：

import pickle

with open('filename.pkl', 'rb') as f:
    data = pickle.load(f)

如果你仍然遇到问题，可以尝试使用更高版本的pickle或者使用其他序列化库，如json或msgpack。

magic_number = pickle_module.load(f, **pickle_load_args) _pickle.UnpicklingError: could not find MARK

This error occurs when unpickling a Python object using the pickle module. It means that the pickle data being loaded does not have the expected format and is missing a crucial marker.

Here are some possible reasons for this error:

1. The pickle data was not created using the same version of Python as the one being used to unpickle it. This can cause compatibility issues.

2. The pickle data was corrupted during transmission or storage. This can cause missing or incomplete markers.

3. The pickle data was tampered with or modified, causing it to lose its integrity.

To fix this error, you can try the following:

1. Check that the pickle data being loaded is valid and was created using the same version of Python as the one being used to unpickle it.

2. Verify that the pickle data has not been corrupted or tampered with by comparing it to a known good copy.

3. Try using a different serialization library or format to store and load your data, such as JSON or YAML.

_pickle.UnpicklingError: could not find MARK

这个错误通常表示在反序列化Python对象时出现了问题。可能是因为你正在尝试反序列化一个不是Python对象的文件，或者文件已经损坏。

尝试检查文件是否已经损坏或者尝试使用其他方法来反序列化Python对象。如果你正在使用pickle模块进行序列化和反序列化，可以尝试使用不同的协议版本来解决问题。你可以尝试升级或降级使用的协议版本。例如，你可以使用较新的协议版本，如pickle.HIGHEST_PROTOCOL，或者使用较旧的协议版本，如pickle.DEFAULT_PROTOCOL。
