The system cannot find the file specified.

and no .dll file is extracted. Thanks for the help!

Error with installation on Mac M1

I'm trying to install pyPhotoDNA on a Macbook Pro with Apple M1 chip, MacOS Monterey version 12.6

I run these 3 commands:

git clone https://github.com/jankais3r/pyPhotoDNA.git
cd pyPhotoDNA
sh install.sh

install.sh script outputs this:

Welcome to the pyPhotoDNA installer.
The script will now setup a pyPhotoDNA environment for you. Please be patient.

To generate a PhotoDNA hash, run: python3 generateHashes.py

Then run python script after changing filepath:
python3 generateHashes.py
Outputs this (the dlopen error is repeated for each image, removed the rest for brevity):

Generating hashes for all images under images/
Starting processing using 8 threads.
dlopen(*path*/pyPhotoDNA/PhotoDNAx64.so, 0x0006): tried: '*path*/pyPhotoDNA/PhotoDNAx64.so' (no such file)
Results saved into *path*/pyPhotoDNA/hashes.csv
Generated hashes for 29 images in 0 seconds.

And the hashes.csv file is empty.

includes a huge library that I don't need ... Isn't there any PhotoDNA alike Python implementation out there?
