AttributeError: module 'pandas' has no attribute 'ewm'

Im using the latest pandas version. I have tried pd.ewm and pd.ewma but with no luck

Thanks

[ray-bun]

Any help pls? Thank you

Should be pd.ewma. Please show me the error when you try ewma. Also try the following thread: https://github.com/pandas-dev/pandas/issues/14666

[ray-bun]

Error below: test.py", line 42, in ups_avg = pd.ewma(ups, span=RSI_N)[-1] AttributeError: module 'pandas' has no attribute 'ewma'

Sorry, based on that thread what am I changing?

[sshashank124]

Hmmm even if ewma doesn't work, ewm should still be available in the latest pandas version as you can see here: https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.ewm.html. Make sure you have pandas installed correctly.

[ray-bun]

I have installed correctly and it is showing in my pip3 list. What version are you using? Could you try it with your latest version? I'm on Pandas 23.4 and can confirm that it doesnt work AttributeError: module 'pandas' has no attribute 'ewm'

If i try this ups_avg = pd.DataFrame.ewm(ups, span=RSI_N)[-1] downs_avg = -pd.DataFrame.ewm(downs, span=RSI_N)[-1]

Traceback (most recent call last): File "C:/Users/xx/PycharmProjects/rsi/rsi_1min_candle.py", line 128, in main_run() File "C:/Users/xx/PycharmProjects/rsi/rsi_1min_candle.py", line 120, in main_run if check_rsi(BASE_ASSET) >= 72: File "C:/Users/xx/PycharmProjects/rsi/rsi_1min_candle.py", line 72, in check_rsi ups_avg = pd.DataFrame.ewm(ups, span=RSI_N)[-1] File "C:\Users\xx\PycharmProjects\rsi\venv\lib\site-packages\pandas\core\generic.py", line 8924, in ewm axis = self._get_axis_number(axis) AttributeError: 'numpy.ndarray' object has no attribute '_get_axis_number'

[ray-bun]

if I run it with Pandas 0.18.0 FutureWarning: pd.ewm_mean is deprecated for ndarrays and will be removed in a future version downs_avg = -pd.ewma(downs, span=RSI_N)[-1]

[ray-bun]

still an issue, any help pls?

[sshashank124]

I wasn't able to figure out the problem. I would suggest updating that line of code to use the new API. You can ask on StackOverflow for how to achieve the same functionality with other library methods

[antoinecomp]

ewm is a Dataframe function now, no more a top one. It changed to pd.Dataframe.ewm(com=None, span=None, halflife=None, alpha=None, min_periods=0, adjust=True, ignore_na=False, axis=0) according to the docs.

Hi, did you have any solution for this? Im trying to calculate RSI with binance client. thanks
