Error in Main Tutorial stage

[khunyung]

Hello,

I'm a beginner to python and I was trying to follow the main tutorial on pycharm and it all seemed fine until I reached this stage

**# Basics
import os
import sys
import time
from matplotlib import pyplot as plt
import arviz as az # Visualization
import pytensor # Graph-based tensor library
import hssm

import hddm_wfpt
import bambi as bmb

pytensor.config.floatX = "float32"

from jax.config import config

config.update("jax_enable_x64", False)**

I got this error
Traceback (most recent call last):

Could you please help? Thank you and apologies in advance!

Hi,

This is caused by breaking changes in numpy 1.26 that is incompatible with the Pytensor codebase. You can downgrade numpy by pip install numpy==1.24.3 to resolve the conflict.

Thanks!
