nboost-index in docker container fails with `'ascii' codec can't decode byte 0xe2`

[marcinczeczko]

Hi, I tried to run both elastic & nboost as docker containers as follows

docker run -d -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:7.4.2 docker run -d -p 8000:8000 koursaros/nboost:latest-pt --uhost host.docker.internal --uport 9200

However, when I tried to index travel.csv within the container it fails with the error docker exec -it <nboost-container-nameorid> nboost-index --host=host.docker.internal --file /opt/conda/lib/python3.6/site-packages/nboost/resources/travel.csv --index_name travel --delim ,

But, If I run nboost on my macos the indexer for the same file works just fine.

Any ideas, what might went wrong ?

Check what the default and preferred encodings are.

Run a python repl and the following lines

import sys
import locale

print(sys.getdefaultencoding())
print(locale.getpreferredencoding())

Compare your MacOS to Docker. I still haven't figured out why, but it doesn't give me the error when I manually set the encoding using this:

with open(filename, 'r', encoding='encoding_name') as f:

You'll have to modify helpers.py and maybe one other file.

I'd try something else because this repo looks abandoned
