Aborted!

adamwaite

My. backtest command is suddenly just outputting "Aborted!" before anything else. It was working fine before - not sure what's happened? It's as if it's not got to the python yet. Like a db error or something?

Saleh

What is the full error? Is there any traceback or something?

adamwaite

Yeah I had a look here and it's not even getting to the clear screen code -> https://github.com/jesse-ai/jesse/blob/ed23304898c89ef68e3b28b9719e55cbf39fd9ec/jesse/modes/backtest_mode/__init__.py. It just says "Aborted!" as if I have used Ctrl+C. Weird. Going to re-build my env.

adamwaite

Damn - a whole new environment from the Docker image and I'm still getting the error.

Command:
jesse backtest 2020-01-01 2020-05-20 --debug

Env: macOS with Docker install.

Other commands work ok (e.g routes or import-candles).

I had a look in https://github.com/jesse-ai/jesse/blob/ecf026abeb0503488379236120848f850597e7bc/jesse/__init__.py#L64 and validate_cwd() is being called - because running it in a non-jesse directory throws the expected error.

So strange was working fine until yesterday.

nerdy

Are you running it within a Jesse project?

adamwaite

nerdy yeah. Strange was working fine until yesterday. Routes remained the same. Will try debugging properly tomorrow. Can I ask pip to point to a local version?

Saleh

adamwaite Yes. Just pull the repository, cd into it and instead run pip install -e .
That way your changes will effect makes it easy for debugging

nerdy

Is postgres running?

adamwaite

Saleh Awesome thanks. Debugging local and narrowed it down to this line: from jesse.modes import backtest_mode, and in modes.init from jesse.services.cache import cache, then to self.db = pickle.load(f) in cache.init.

I deleted all the Pickle files in storage/temp and we're back in business!

Saleh

adamwaite That's good to know. Thank you!

I think I had a similar error some time ago. Now it makes sense. The time i had this error it solved itself (as it seemed) as i changed the backtesting dates. I think if you Ctrl C during the caching of the candles or the cached candles (pickle file) gets corrupted any other way, this error occurs.

nerdy

I have had this happen also after a ctrl-c. Cleared the temp directory and all was well again.

Saleh

I guess I should create a clear cache command then
