How to deal with SettingWithCopyWarning in Pandas
(20 answers)
Closed 1 year ago.
Please suggest the right way of doing the following.
data_tr['loss'] = data_tr['loss'].apply(lambda x:x**0.25)
<ipython-input-368-59c3c700212e>:1: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead
See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
data_tr['loss'] = data_tr['loss'].apply(lambda x:x**0.25)
Have you tried what's suggested?
data_tr.loc[:,'loss'] = data_tr.loc[:,'loss']**0.25

ios programming - Data argument not used by format string
(2 answers)
Closed 6 years ago.
Hi there I'm trying to do an NSLog but what I want to see is what it's inside of my dictionary like this.
NSLog(#"diccionario", diccionario);
And this warning appears:
Data argument not used by format string
The diccionario object contains data from a server so like I said I want to print in the console the info that diccionario contains, because is not printing anything.
Thanks.
NSLog(#"diccionario : %#", diccionario);
Should be the solution.

Closed 6 years ago.
I have an Iterator<Item=io::Result<u8>> that I'd like to convert to io::Result<Vec<u8>>.
iter.map(|x| x.unwrap()).collect::<Vec<u8>>()

#aspex thanks for you help, it's
let fold: io::Result<Vec<_>> = iter.collect();

Is it possible to add on to the text of a label without changing existing text? I'm new to mac development in Xcode so any help is appreciated.
Yes and no. Basically, you replace the text with a new string that includes the old text
self.myLabel.text = [self.myLabel.text stringByAppendingString:#"more stuff"];
