问题
I have installed the latest version of nlpnet library (http://nilc.icmc.usp.br/nlpnet/). Then, when I try to use nlpnet POSTagger according to the follwoing example, I get an error:
import nlpnet
tagger = nlpnet.POSTagger('/path/to/pos-model/', language='pt')
Error:
Traceback (most recent call last):

raise ValueError("Object arrays cannot be loaded when "
ValueError: Object arrays cannot be loaded when allow_pickle=False
I also tried to install nlpnet again in a different virtual environment, but the error persists. I'm not sure if this is a incompatibility problem, a bug in the lib or an installation issue.
Any suggestions?

I am also using nlpnet, and I had the same problem. Searching on Google, I found this question on Stack Overflow. Following one of the answers, I downgraded numpy to version 1.16.1, and it worked for me.
pip install numpy==1.16.1
Hope it helps you.
