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.
