Use KFold split to fit model return "Not in index"


By : user2175653
Date : October 14 2020, 08:10 PM
I wish this helpful for you From what I see, the index of your dataframe starts at 10 and not at 0, and as you said the split from sklearn uses index starting from 0. One solution is to reset the index of your dataframe with :
code :
df = df.reset_index(drop=True)
for train_index, test_index in kf.split(X_train, y_train):
   model.fit(X.iloc[train_index], y[train_index])
   y_pred = model.predict(X.iloc[test_index])
for train_index, test_index in kf.split(X_train, y_train):
   model.fit(X.values[train_index], y[train_index])
   y_pred = model.predict(X.values[test_index])

MATLAB - Difference between "k" and 'kfold" partition type for cvpartition


By : Nicolás Herrero
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further There is absolutely no difference. The cvpartition class constructor just checks the n characters you've provided against the first n characters of the standard method names. So 'k', 'kfo', and 'kfold' are all equivalent arguments.

Ruby ARGF & RegEx: How to split on paragraph carriage return "\r\n" but not end of line "\r\n"

Hope that helps Beware when you do ARGF.each do |text|, the text will be every single line, NOT the whole text block.
You can provide ARGF.each a special line separator, it will return you two "lines", which are the two paragraphs in your case.
code :
paragraphs = ARGF.each("\r\n\r\n").map{|p| p.gsub("\r\n","")}

Trouble with "show" and "index" routes in model with many to one relationship Ruby on Rails

Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further I feel like the solution to this is actually quite simple but I can't figure it out. , Pass piece id to link to helper as piece_section_path need two params
code :
piece_section GET    /pieces/:piece_id/sections/:id(.:format)      sections#show
<%= link_to section.name, piece_section_path(@pieces, section), class: 'section_name' %>

"ERROR in loader Users/abc/node_modules/babel-core/index.js?{"presets":["react"]} didn't return

will help you When I'm doing webpack I'm getting into this error: , babel-core is the core of babel, it's not a loader. You should use :
code :
loader: 'babel-loader' // Or just 'babel'

Indices that KFold split method return for a DataFrame is it iloc or loc?

this will help You need DataFrame.iloc for select rows by positions:
Sample:
code :
np.random.seed(100)
df = pd.DataFrame(np.random.random((10,5)), columns=list('ABCDE'))
#changed default index values
df.index = df.index * 10
print (df)
