ModuleNotFoundError : Pyarmor 9.1.1

[ckvasan]

I have simple python project

first_proj
f1
- init.py
- test.py
main.py

===================

test.py

def test() :
print("This is test fn")

main.py

from f1 import test as t
t.test()
print("main")

=======================
Run the below to obfuscate :
pyarmor gen -r main.py

Obfuscation runs successfully
