@alexeigor I got the same error on kaggle too

@support Thx for ur reply

@support I know it sounds strange, but I want to use the distances between the sun and moon and related astronomical data for each trading day as features for my model. The data sources are obtained through mathematical calculations using an open-source Python module, rather than through web scraping.
Here is the link to this Python open-source module.

@support I got it. Thanks for ur reply

I submitted my strategy
but it failed due to data loading from qnt
the output shows that the data loading from qnt ranges from 2004-11-01 to 2005-12-30
the code I submitted is:
start_date, end_date, prepare_date = '2006-01-01', datetime.now().strftime('%Y-%m-%d'), '2004-11-01'
data = qndata.stocks_load_spx_data(min_date = prepare_date, max_date = end_date)
but qnt didn't load the data after 2006-01-01
@support
I would like to know how to fix the problem

After I upgrade to the latest version of qnt library(0.0.406)
An error appears
"Exception: can't download assets"
@support Is there a bug in the latest version of qnt?

@support Thanks for ur help
Is there a way to turn off the warning from the outside of the qnt module? I hope that I can just add a line in my strategy code to call something in the qnt module to remove the warning.

I'm using partial data for testing the performance for machine learning models.
qnt module outputs such warning:
WARNING: some dates are missed in the portfolio_history
I'd like to turn off this warning
But I don't know how to do
Can @support give an example for how to turn off this specific warning?

@support
Do u mean that I should not have these line in my codes?
Should I delete those lines(environ['...'] = '...')?

@omohyoid

Two strategies failed but no error messages show
I don't what happened to these strategies
The strategies are # 17190184 and # 17190033
Can @support take a look at them

@support I got it
Thanks for ur reply

Today I have tried lots of times to log in and attempted to submit my strategies but when I click "Development", the website lagged and logged me out automatically.
Can @support fix this error?
Thank u very much

I have multiple strategies with high correlation
Can these strategies participate in the contest?
@support

@support Thx for ur reply
I'll try it

@illustrious-felice It still fails to install pandas 1.2.5 in GCP

@illustrious-felice Thanks for ur suggestion, I'll try it

@support
Do you mean I need to run the commands like this?

I'm using kaggle to test my strategies on the cloud.
Today an error occurs:
KeyError: "cannot represent labeled-based slice indexer for coordinate 'time' with a slice over integer positions; the index is unsorted or non-unique"

Then I check the installation of the packages. I found that pandas 1.2.5 was not successfully installed, which cause the error.


The error results from the wrong version of pandas, but I cannot install pandas 1.2.5, so I cannot fix the error.
Does anyone know how to install pandas 1.2.5 on kaggle?
I may need some help from @support
Thx very much

I submitted the strategy after I use qnout.clean() and qnout.check(). I also wrote qnout.write(wts_xr) in a separate cell.
But I still get "Missed call to write_output (...)" error after submission.
I don't know what happened during the checking.
I suspected that the output path of the weights has changed, which results in the error of missed call.
The default path is 'fractions.nc.gz', so I use it as the output path.
What is the correct string of the output path for Q21?
My submission number is # 17155999, can @support take a look at it to help me figure out what's wrong there?
Thx very much
