pyarmor and library dependencies

Question

I am trying to obfuscate my codes using PyArmor 7; the code uses Librosa and appearance librosa also uses lazy_loader.

my code uses a series of code under xa_dsp_tools folder.

so I use

pyarmor obfuscate --recursive \
         --output dist/xa_dsp_tools xa_dsp_tools/__init__.py \

pyarmor obfuscate --recursive \
                        --output dist/src src/main.py \

this results in a dist folder mirroring these two src and xa_dsp_tools folder;

however when I run my code using python dist/src/main.py

I get

Traceback (most recent call last):
  File "/Users/alka/Library/Caches/pypoetry/virtualenvs/plusplus-ETvGGZ8p-py3.10/lib/python3.10/site-packages/lazy_loader/__init__.py", line 193, in load

During handling of the above exception, another exception occurred:

I wonder how
