  • python - How to read pickle file? - Stack Overflow
    If you simply do pickle load you should be reading the first object serialized into the file (not the last one as you've written) After unserializing the first object, the file-pointer is at the beggining of the next object - if you simply call pickle load again, it will read that next object - do that until the end of the file
  • pickle - Understanding Pickling in Python - Stack Overflow
    The pickle module implements a fundamental, but powerful algorithm for serializing and de-serializing a Python object structure Pickling - is the process whereby a Python object hierarchy is converted into a byte stream, and Unpickling - is the inverse operation, whereby a byte stream is converted back into an object hierarchy

    It is surprisingly easy to overwrite a pickle file if you're copying and pasting code For example the following writes a pickle file: pickle dump(df,open('df p','wb')) And if you copied this code to reopen it, but forgot to change 'wb' to 'rb' then you would overwrite the file: df=pickle load(open('df p','wb')) The correct syntax is
  • python - How to use pickle to save sklearn model - Stack Overflow
    In the specific case of scikit-learn, it may be better to use joblib’s replacement of pickle (dump load), which is more efficient on objects that carry large numpy arrays internally as is often the case for fitted scikit-learn estimators: Save: import joblib joblib dump(model, "model joblib") Load: model = joblib load("model joblib")
  • How to pickle and unpickle to portable string in Python 3
    If space efficiency really matters, you definitely want to use pickle protocol 4 and environb when possible, or maybe even pickle protocol 4 plus bzip For Windows, I'd test pickle protocol 4 plus bzip plus base64 vs pickle protocol 0, but my guess would be that the former is smaller
