'charmap' codec can't encode character '\u01b0' in position

Rasa Open Source
1

when I run the command

rasa run actions --actions actions rasa interactive -m models/20190515-135859.tar.gz --endpoints endpoints.yml there is an error

UnicodeEncodeError: ‘charmap’ codec can’t encode character ‘\u01b0’ in position 1441: character maps to

I try to run

set PYTHONIOENCODING=‘utf8’

but i doesn’t work

2

what version of python and rasa are you using?

3

python 3.7.3 and Rasa 1.1.6

4

can you tell me the alternative for

export PYTHONPATH=/path_to_your_project_dir/:$PYTHONPATH

in window ? When i cd to another Rasa project to run, the command line keeps showing the errors related to the previous project

Hi @TQuy,

Are you sure you encoded your endpoints.yml in utf-8 when you saved it?

6

I am not sure, I just copy it from Rasa example and save it in my folder, not sure how to encode it in utf-8 endpoints.yml (1.4 KB)

7

Can you post the full stacktrace please?

I run

rasa run actions

on other window

Hi @TQuy,

I think this is a Windows-related bug. Could you try running rasa interactive with the --skip-visualization flag and let me know if you still encounter this error?

10

It fixes the problem. However, I have a new one for you :wink: I face it when run the command rasa interactive -m models/20190515-135859.tar.gz --endpoints endpoints.yml and chat 1 message
