ModuleNotFoundError: No module named 'scipy'

I created a virtual environment in Miniconda for Python version 3.8.16 and installed all dependencies from the requirements.txt file via pip3 install. All packages were installed successfully. However, when I try to start the program with the command 'python3 Retina.py -d samples/webex/webex_sample.pcapng', as seen in the documentary, I get an error.

(retina2) C:\...\Retina>python3 Retina.py -d samples/webex/webex_sample.pcapng

ModuleNotFoundError: No module named 'scipy'

scipy was already installed inside the environment but I got the same error:
Requirement already satisfied: scipy in c:....\anaconda3\envs\retina2\lib\site-packages (1.10.1)
Requirement already satisfied: numpy<1.27.0,>=1.19.5 in c:....\anaconda3\envs\retina2\lib\site-packages (from scipy) (1.22.0)
