access denied to prophet/stan_model/prophet_model.bin

Hello everyone,

Need your helps to resolve an issue when installing and packaging prophet library to use it for aws lambda layer.
I already do this work twice with python3.5 and python3.6. But for now in python 3.9 ,
I have the below problem **to access to prophet/stan_model/prophet_model.bin** when calling prophet library in my aws lambda.
I try installation with pip3.9 and sudo pip3.9 but I have the same issue. But , i have good import because when i do

import prophet
print(dir(prophet))

**I have :**
(['Prophet', '__builtins__', '__cached__', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__path__', '__spec__', '__version__', 'diagnostics', 'forecaster', 'hdays', 'make_holidays', 'models', 'plot']

I do this work on :

1. linux Debian -amd64 (4.9.320-2 (2022-06-30) x86_64)
2. python3.9
3. prophet 1.1

**So thanks a lot for your help:**
**NB : I install it on the linux machine and it works well . It is only when i use it on aws lambda that i have this issue**
