grid_search_forecaster_multiseries - error

[AVPokrovsky]

Hi, I upgraded to the last version and got this error from grid_search_forecaster_multiseries. It worked with previous version with the same data (I don't remember which version was used before)

210 models compared for 1 level(s). Number of iterations: 210. lags grid: 0%| | 0/7 [00:00<?, ?it/s] params grid: 0%| | 0/30 [00:00<?, ?it/s] lags grid: 0%| | 0/7 [00:00<?, ?it/s]TypeError: DataFrame.reset_index() got an unexpected keyword argument 'names'

Hello @AVPokrovsky,

Thanks for contacting us, the problem here is that the argument names in reset_index() was included in pandas 1.5.

Our requirements start with pandas 1.2, we will fix it in skforecast 0.13.

In the meantime, install pandas 1.5 or higher. This should fix the bug.

Hope this helps!

It seems this is not a reason. I already have 1.5.1

This is strange, looking at the pandas documentation, names was introduced in this version:

https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.reset_index.html

Could you please try with pandas 2.0?

Finally I resolved this issue changing pandas version. I got another one with RNN regressor (below). It also appears with you code examples on RNN. It was resolved when I downgraded Tensorflow from 2.16.1 to 2.15.1

Input shape of the regressor should be Input(shape=(lags, n_series))

I open a new issue regarding the RNN regressor @FernandoCarazoMelo

how you managed to install the older version 2.15.1? when i tried to do that i gett the below error :

ERROR: Could not find a version that satisfies the requirement tensorflow==2.15.1 (from versions: 2.16.0rc0, 2.16.1, 2.16.2, 2.17.0rc0, 2.17.0rc1, 2.17.0) ERROR: No matching distribution found for tensorflow==2.15.1

Hi, @bassamabdelghani ,

Which Python version are you using?
