Python pickle error: UnicodeDecodeError

I"m trying to do some text classification using Textblob. I"m first training the model and serializing it using pickle as shown below.

import pickle
from textblob.classifiers import NaiveBayesClassifier

with open("sample.csv", "r") as fp:
     cl = NaiveBayesClassifier(fp, format="csv")

f = open("sample_classifier.pickle", "wb")
pickle.dump(cl, f)
f.close()

And when I try to run this file:

import pickle
f = open("sample_classifier.pickle", encoding="utf8")
cl = pickle.load(f)    
f.close()

I get this error:

UnicodeDecodeError: "utf-8" codec can"t decode byte 0x80 in position 0: invalid start byte

Following are the content of my sample.csv:

My SQL is not working correctly at all. This was a wrong choice, SQL

I"ve issues. Please respond immediately, Support

Where am I going wrong here? Please help.

How can I make a time delay in Python?

5 answers

I would like to know how to put a time delay in a Python script.

Answer #1

import time
time.sleep(5)   # Delays for 5 seconds. You can also use a float value.

Here is another example where something is run approximately once a minute:

import time
while True:
    print("This prints once a minute.")
    time.sleep(60) # Delay for 1 minute (60 seconds).

Answer #2

You can use the sleep() function in the time module. It can take a float argument for sub-second resolution.

from time import sleep
sleep(0.1) # Time in seconds

How do I delete a file or folder in Python?

Answer #1

os.remove() removes a file.
os.rmdir() removes an empty directory.
shutil.rmtree() deletes a directory and all its contents.

Path objects from the Python 3.4+ pathlib module also expose these instance methods:

pathlib.Path.unlink() removes a file or symbolic link.
pathlib.Path.rmdir() removes an empty directory.

StackOverflow is always a bit confusing 😭 Python pickle error: UnicodeDecodeError is not the only problem I encountered. Checked yesterday, it works!
