bdiamante s answer may only partially help you   If you still get a message after you ve suppressed warnings  it s because the pandas library itself is printing the message   There s not much you can do about it unless you edit the Pandas source code yourself   Maybe there s an option internally to suppress them  or a way to override things  but I couldn t find one   For those who need to know why    Suppose that you want to ensure a clean working environment   At the top of your script  you put pd reset option  all     With Pandas 0 23 4  you get the following   gt  gt  gt  import pandas as pd  gt  gt  gt  pd reset option  all   html border has been deprecated  use display html border instead  currently both are identical   C  projects stackoverflow venv lib site-packages pandas core config py 619  FutureWarning  html bord er has been deprecated  use display html border instead  currently both are identical     warnings warn d msg  FutureWarning     boolean     use inf as null had been deprecated and will be removed in a future     version  Use  use inf as na  instead   C  projects stackoverflow venv lib site-packages pandas core config py 619  FutureWarning    boolean     use inf as null had been deprecated and will be removed in a future     version  Use  use inf as na  instead     warnings warn d msg  FutureWarning    gt  gt  gt   Following the  bdiamante s advice  you use the warnings library   Now  true to it s word  the warnings have been removed   However  several pesky messages remain   gt  gt  gt  import warnings  gt  gt  gt  warnings simplefilter action  ignore   category FutureWarning   gt  gt  gt  import pandas as pd  gt  gt  gt  pd reset option  all   html border has been deprecated  use display html border instead  currently both are identical      boolean     use inf as null had been deprecated and will be removed in a future     version  Use  use inf as na  instead    gt  gt  gt   In fact  disabling all warnings produces the same output   gt  gt  gt  import warnings  gt  gt  gt  warnings simplefilter action  ignore   category Warning   gt  gt  gt  import pandas as pd  gt  gt  gt  pd reset option  all   html border has been deprecated  use display html border instead  currently both are identical      boolean     use inf as null had been deprecated and will be removed in a future     version  Use  use inf as na  instead    gt  gt  gt   In the standard library sense  these aren t true warnings   Pandas implements its own warnings system   Running grep -rn on the warning messages shows that the pandas warning system is implemented in core config init py    grep -rn  quot html border has been deprecated quot  core config init py 207 html border has been deprecated  use display html border instead  Further chasing shows that I don t have time for this   And you probably don t either   Hopefully this saves you from falling down the rabbit hole or perhaps inspires someone to figure out how to truly suppress these messages

Warnings are annoying  As mentioned in other answers  you can suppress them using   import warnings warnings simplefilter action  ignore   category FutureWarning    But if you want to handle them one by one and you are managing a bigger codebase  it will be difficult to find the line of code which is causing the warning  Since warnings unlike errors don t come with code traceback  In order to trace warnings like errors  you can write this at the top of the code   import warnings warnings filterwarnings  error     But if the codebase is bigger and it is importing bunch of other libraries packages  then all sort of warnings will start to be raised as errors  In order to raise only certain type of warnings  in your case  its FutureWarning  as error  you can write   import warnings warnings simplefilter action  error   category FutureWarning
