Prevent showing debugging log info inside ipython shell

Question

I'm using scrapy shell inside virtualenv. IPython is installed inside virtualenv. When I start scrapy shell using

 scrapy shell 'https://example.com'

and press tab for autocomplete suggestions, it shows a lot of debug information. How can I disable this?

Answer 1

https://github.com/ipython/ipython/issues/10946 looks like it's reported bug here.

In case you need debug logging in ipython, try to logging.getLogger('parso.cache').disabled=True logging.getLogger('parso.cache.pickle').disabled=True

and keep wait for parso update

Answer 2

Try doing this to set the logging level to WARNING:

import logging

logging.getLogger().setLevel(logging.WARNING);

Any log messages of level INFO or DEBUG shouldn't appear anymore. You can also set the log level to logging.ERROR. Then WARNING messages won't appear as well.

Good luck!

Answer 3

You can use the -L command-line option to change the log level to INFO:

scrapy shell -L INFO https://example.com
