Test 1.1.2
C:\Users\742093\AppData\Roaming\Python\Python36\site-packages\pandas\core\indexing.py:670: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame
See the caveats in the documentation: https://pandas.pydata.org/pandas-docs/stable/user_guide/indexing.html#returning-a-view-versus-a-copy
iloc._setitem_with_indexer(indexer, value)
Test 1.1.3
print("Test 1.1.2")
df = pd.read_csv( r''+file+'', sep=";", engine='python' ) #open the file and read
print("Test 1.1.3")
As you can see the warning appears right at the read_csv-line. But I have no clue what this warning means in my case or how to fix it. It must have something to do with the data in the file I'm loading (I load other files to with no problem).
