Passing list-likes to .loc or [] with any missing labels is no longer supported

I want to create a modified dataframe with the specified columns. I tried the following but throws the error "Passing list-likes to .loc or [] with any missing labels is no longer supported"

# columns to keep
filtered_columns = ['text', 'agreeCount', 'disagreeCount', 'id', 'user.firstName', 'user.lastName', 'user.gender', 'user.id']
tips_filtered = tips_df.loc[:, filtered_columns]

# display tips
tips_filtered

Thank you

It looks like Pandas has deprecated this method of indexing. According to their docs:

This behavior is deprecated and will show a warning message pointing to this section. The recommended alternative is to use .reindex()

Using the new recommended method, you can filter your columns using:

tips_filtered = tips_df.reindex(columns = filtered_columns).

NB: To reindex rows, you would use reindex(index = ...) (More information here).

Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.
