double free or corruption (!prev): 0x00005613ec89a910 ***

Hi, I have successfully run the codes with the guide of tutorial Getting Start.
I tried to run deepmatcher with the dataset of structured walmart_amazon and I reformat the csv file like the itunes-amazon dataset from Getting Start tutorial. But when I run this code :

train, validation, test = dm.data.process(
path='.',
train='train.csv',
validation='validation.csv',
test='test.csv')

it reports an error as :

Computing principal components
0% [######] 100% | ETA: 00:00:00
Total time elapsed: 00:00:01
*** Error in `~/anaconda3/bin/python': double free or corruption (!prev): 0x00005613ec89a910 ***
Aborted (core dumped)

Do you have any ideas of what is wrong?
