UnsupportedFunctionCall: numpy operations are not valid with resample. Use .resample(...).sum() instead

[Barkan97]

I ran the simple code below and got an error: qs.reports.full(returns=equity_return, benchmark=benchmark_return, output='report.html', title='Strategy') (with equity_return and benchmark_return being Series and timeframe M30) and I get the following error:

Passing additional kwargs to DatetimeIndexResampler.sum has no impact on the result and is deprecated. This will raise a TypeError in a future version of pandas.

Please guide me how to fix it, thank you !!!

It has been a long time, the first time I used it, I encountered such a problem, so far have not run through helloworld

I downloaded the library code, and then based on https://github.com/ranaroussi/quantstats/pull/375/files https://github.com/bbalouki/quantstats/blob/bbs-dev/quantstats/_plotting/core.py Line 292

  if resample:
       returns = returns.resample(resample).last() if compound else returns.resample(resample).sum()
       if isinstance(benchmark, _pd.Series):
           benchmark = benchmark.resample(resample).last() if compound else benchmark.resample(resample).sum()
           

Edit, Then run it in your local library directory

pip install -e.

Then it worked

good stuff, thank you for the fix

I got the error only when I used quantstats.reports in jupyter notebook. So, with direct python scripts it works fine.

Closing this issue as it's older than 2025 and has been specifically addressed in release 0.0.64. The pandas resampling compatibility issues have been resolved with the comprehensive compatibility layer implementation.
