no prodigy.json file


I am french and i will do my best in english :wink:
I bought prodigy yesterday, installation worked but prodigy.json is not present.
I tried to create it but when i start :
python3.6 -m prodigy news_headlines test_dataset “Silicon Valley” -F /home/a.dumas/python/code/prodigy/

if i create my own prodigy.json file :

Traceback (most recent call last):

File “/usr/lib64/python3.6/”, line 638, in _parse_args
a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not boolstrong text

if not => prodigy say “Error : Can’t fetch project and tasks, make sure the server is running correctly”

OS is CentOS 7.4 x64.

Do you have an idea ?


Merci! :blush:

Thanks for the report! I think the problem here is that Prodigy will look for a .prodigy directory in your user home that contains a file prodigy.json. If it doesn’t exist, Prodigy will try to create it – and for some reason, this seems to fail in your case. (Maybe it’s something related to user permissions?) You can always use the PRODIGY_HOME environment variable to specify a custom home directory for Prodigy.

Did you copy-paste the prodjgy.json defaults from the docs? I think we made a mistake in our prodigy.json docs and/or the way the server reads in this value of "instructions". So if your prodigy.json has "instructions": false or something similar, try removing that!

We currently check if "instructions" exists and then assume it’s a file – instead, we should check if it exists and is a string (and not false) before using it. That’s why it fails on this line:

help_path = Path(config[‘instructions’])

i am using PRODIGY_HOME environment variable.
echo $PRODIGY_HOME => /home/a.dumas/prodigy (created manually too)

And i copy-paste the prodigy.json default from website (

Instructions has been removed and it’s ok now.

Thanks for your help.

Thanks for updating, glad it worked! I’ve already fixed the problem in Prodigy and it will be included in the next release :+1:

Edit: Just released v1.4.1, which should handle "instructions": false properly!
