comparing entire data upto 5 decimal places using numpy.testing.assert_almost_equal and error output as desire pattern?

I have a data frame as

ent_id  buy new_perc_buy    sell    new_perc_sell
123 0.116211962 0.116198415 0.496314325 0.496256466
124 0.007214061 0.00721322  0.153933545 0.1539156
125 0.003410283 0.003409886 0.499973272 0.499914987
126 0.231587543 0.231560545 0.699696021 0.699614452
127 0.056794334 0.056787713 0.235372057 0.235344618
128 0.130377754 0.130362555 0.187575903 0.187554036
129 0.998294858 0.99817848  0.917661563 0.917554585
130 0.208247701 0.208223424 0.575032323 0.574965287

now I have to match buy with new_perc_buy (upto 5 decimal places) similarly sell with new_perc_sell (upto 5 decimal places) with correspond to ent_id and if it does not meet the decided condition it fails

as I am using numpy.testing.assert_almost_equal

import numpy 
numpy.testing.assert_almost_equal(df_ss['rnk_perc_buy'],df_ss['new_perc_rnk_perc_buy'], decimal=5, err_msg='false', verbose=True) 

I am getting this error

ValueError                                Traceback (most recent call last)

ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

also there any way by which I get error output like below

AssertionError: 
Arrays are not almost equal to 5 decimals for **ent_id 123**
 ACTUAL: 0.116211962
 DESIRED: 0.116198415
