At the end of notebook,when time series came in, lines 15 and 16, some errors happen and no temperature fixing is possible:

hi @tizianoct2000

is this ungraded lab?

also if you are trying to copy a dataframe, then the error log is mentioning to use

.loc[row_indexer, col_indexer] = value

Hello,

yes it is in course AI for good -AI and climate change, week 2. I’m not trying to do anything, it is just an error thrown by the utils.py when executing some of its function , when the main program apparently call them. I don’t know if this erros would compromise any of the following labs in this course, the first effect is to deny the temperature fixing in this lab, so I signal them to anyone who could patch them.

Hi @tizianoct2000,

These are “warnings” (SettingWithCopyWarnings), not execution “errors”.

An error crashes the program; a warning is an advisory notice that the code is running but might produce unpredictable results.

In the context of this lab, these can be safely ignored.

Best,
Mubsi
