QST: How to disable s3fs
I installed s3fs to try it out.  I have removed it from my environment after deciding against it.  However, someone upstream uses Pandas.  Despite s3fs having been removed and no s3fs imports existing anywhere in the entire code base, Pandas wants to use s3fs.  This causes my application to fail.  Is there a way to correct this without having to recreate my entire development environment?
