PMDARIMA: unable to use pmdarima in google collab #591

Describe the bug

Description:

I am encountering a persistent ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject error specifically when importing auto_arima from the pmdarima library in Google Colab. This error occurs regardless of the Python environment, NumPy version, or installation method used. Critically, this error persists even when running the code inside a clean Docker container, indicating a potential issue with the pmdarima package itself.

To Reproduce

import numpy as np
import pandas as pd

Create a simple monthly time series with 36 data points

ts = pd.Series(
np.random.randn(36),
index=pd.date_range(start='2020-01-01', periods=36, freq='MS')
)

# This import triggered the binary incompatibility error

from pmdarima import auto_arima

Fit an ARIMA model (with seasonal component)

model = auto_arima(ts,
seasonal=True,
m=12,
trace=True,
error_action='ignore',
suppress_warnings=True)

print("ARIMA order:", model.order)
print("Seasonal order:", model.seasonal_order)

Versions

pmdarima-2.0.4
Linux-6.1.85+-x86_64-with-glibc2.35
Python 3.11.11 (main, Dec  4 2024, 08:55:07) [GCC 11.4.0]
NumPy 2.0.2
SciPy 1.14.1
Scikit-Learn 1.6.1
Statsmodels 0.14.4

Expected Behavior

The model should predict my data.

Actual Behavior

Expected Output

Key Information:

Error: ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject
Trigger: from pmdarima import auto_arima
Environment: Google Colab (Ubuntu 22.04.4 LTS, Python 3.11.11)

Persistence: Error persists even in a Docker container with python 3.9 and numpy 1.23.
Troubleshooting: Extensive troubleshooting steps have been taken, including NumPy downgrades, Conda environments, and installation from source.

Additional Context

Request:

Please investigate this issue, as it appears to be a bug within the pmdarima package or a fundamental incompatibility that persists even in isolated Docker environments.
