I'm getting this error when I run the code same with regressor_multivar.py

I'm using pycharm, and when running the program, it sends the following error message: "ImportError: cannot import name 'cross_validation' from 'sklearn' "
Which command replaced the cross_validation function?

file: random_forests.py
I'm getting the following error:

usage: random_forests.py [-h] --classifier-type {rf,erf}
random_forests.py: error: the following arguments are required: --classifier-type

What should I do? Thanks in advance.

I getting equal results with with using recall_weighted and precision_weighted scorers. What can I do for fix it and get results as in a book? Links for mine and original codes below.
My code , Original code

In your map, the eastern shore of Virginia is incorrectly attributed to Maryland and Virginia is not listed as a Costal State. This is incorrect.

hi, i want to know the values substituted as true labels and pred labels ? How those values are taken?? Thanks

code: classifier.fit(X, y)
TypeError Traceback (most recent call last)
in
1 #Тренировка классификатора
----> 2 classifier.fit(X, y)

TypeError: fit() missing 1 required positional argument: 'y'

And please post the package versions for installation via pip.

This is not working. The entire book is based on line 5, so I cannot proceed. Utilities module does not exist. Can someone please tell me what's wrong?

There is no preprocessing.py in "Chapter 02" or any other chapters of the downloaded code. In the Safari Books Online ebook at the end of chapter 2 [Preprocessing data]: "The code for this entire section is given in the preprocessing.py file."

hello, thanks to authors,Am new to artificial intelligence using python & i'am using this book as my guide, i am learning how Naïve Bayes classifier works,the input file data_multivar_nb.txt is not provided.. i have searched via web but i couldn't get help,so am reaching out for the link so that i can download the file..

when I run chapter 14 vector_quantizer.py,it have the following error message
Error: slice indices must be integers or None or have an index method
when run to the following code
nn = nl.net.newlvq(nl.tool.minmax(data), num_input_neurons, weights

Page 67
from sklearn import cross_validation

Get an import error, looks like it is deprecated.

When running python stocks.py in Chapter 04, it prints:

Traceback (most recent call last):
  File "stocks.py", line 7, in <module>
    from matplotlib.finance import quotes_historical_yahoo_ochl as quotes_yahoo
ModuleNotFoundError: No module named 'matplotlib.finance'

It seems matplotlib.finance has been removed from matplotlib and trasferred to mpl_finance. Moreover, quotes_historical_yahoo_ochl is no longer available in this package due to frequent changes of Yahoo API.

I wonder if you could provide an alternative way to get the stock quotes data, so that the file can be correctly run.

Thank you.

I'm running into errors running this python script located here https://github.com/PacktPublishing/Artificial-Intelligence-with-Python/blob/master/Chapter%2006/code/prime.py

I'm also using this python logpy script found here https://github.com/MHordecki/LogPy

This is the error i receive when I try to run it. Please see below. Any suggestions on what I can be doing wrong. I'm new to python coding.

Good Day!
Hi, i have a problem in line #52 of traffic_prediction.py. Please, you can help me to resolve this error?

I am attempting Logistic Regression classifier. I'm in Spyder/Anaconda so I can edit. I get error: no module named 'utilities'. What's wrong?
