👻 Check our latest review to choose the best laptop for Machine Learning engineers and Deep learning tasks!

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.

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
