NLTK dependency data not available, How to download

I used NLTK package in spider pipeline file. However, the NLTK dependency data is not downloaded in scrapinghub cloud. In local python, we just use nltk.download() to download them. Any way to download the NLTK data on scrapinghub? I paste the processing error as below.

Traceback (most recent call last):
