Numpy: Import from source dir error

I am trying to import Numpy in my mojo project using 
from python import Python

fn main() raises:
    var np = Python.import_module("numpy")
from python import Python

fn main() raises:
    var np = Python.import_module("numpy")
But I get the following Error: 
Unhandled exception caught during execution: Error importing numpy: you should not try to import numpy from
        its source directory; please exit the numpy source tree, and relaunch
        your python interpreter from there.
mojo: error: execution exited with a non-zero result: 1

What mojo version are you using? Please make sure that numpy is visible and is in Python path which you can investigate using sys.path

Hi Ehsan, thanks for the reply! I am using mojo 24.1.0 on Mac Here is my sys.path. I see site-packages so shouldn't it have access to numpy ? 
['', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python310.zip', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10/lib-dynload', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10/site-packages']
['', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python310.zip', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10/lib-dynload', '/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10/site-packages']
I also tried this: 
fn main() raises:
    var sys = Python.import_module("sys")
    _ = sys.path.append("/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10/site-packages/numpy")
    var np = Python.import_module("numpy")
fn main() raises:
    var sys = Python.import_module("sys")
    _ = sys.path.append("/Users/pascaldao/.pyenv/versions/3.10.0/lib/python3.10/site-packages/numpy")
    var np = Python.import_module("numpy")
But I get the same error.
