Pandas series.rank(ascending=False) get rise to SIGSEGV error · Issue #13445 · pandas-dev/pandas (original) (raw)

I read dataframe from hdf5 file and rank it. but It rise to a SIGSEGV.
Maybe it's a numpy or table bug..

Code Sample, a copy-pastable example if possible

import pandas as pd
def test_df_ranks(f):
df = pd.read_hdf(f, key="t")
print (df.shape)
print (type(df))
print (df)
s=df.non_current_asset_to_total_asset
#s.rank() # rank() work properly
s.rank(ascending=False) #rank(ascending=False) crash

Expected Output

I expected work well, but rise to me SIGSEGV error
the stacks as follows.
