prophet uses deprecated numpy np.float/int aliases

[waarmond]

Running the basic car sales example

from pandas import read_csv
from pandas import to_datetime
from fbprophet import Prophet
# load data
path = 'https://raw.githubusercontent.com/jbrownlee/Datasets/master/monthly-car-sales.csv'
df = read_csv(path, header=0)
# prepare expected column names
df.columns = ['ds', 'y']
df['ds']= to_datetime(df['ds'])
# define the model
model = Prophet()
# fit the model
model.fit(df)

fails against my python-numpy 1.26.4 (that's far before 2.0!) with:

  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.10/site-packages/fbprophet/forecaster.py", line 1115, in fit

    raise AttributeError(__former_attrs__[attr])
AttributeError: module 'numpy' has no attribute 'float'.
`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.

  File "/usr/lib/python3.10/site-packages/fbprophet/forecaster.py", line 401, in set_changepoints
    .astype(np.int)
AttributeError: module 'numpy' has no attribute 'int'.

This may be fixed by changing them into float64/int64.

same issue

import pandas as pd from prophet import Prophet from matplotlib import pyplot

class FrcstSucs(object):

def __init__(self):
    pass

def frcst_efe_suc(self, dfdata):

    dfdata.plot()

    model = Prophet()
    model.fit(dfdata)

    dftest = model.predict(dftestdates)
    print(dftest[['ds', 'yhat', 'yhat_lower', 'yhat_upper']])

    model.plot(dftest)
    pyplot.show()
