I was able to solve this by doing

First Install:

brew install libxml2
brew install libxslt
And then doing this:
pip install lxml==4.9.2

I still have the same error on mac m2 max

I'm pretty sure the above commands will work. You may double check your current python env and/or if these packages are installed to the right env.

If I install it the normal manual way (using conda python 3.8), the installation can be successful, however when I run convert on the model I have trained, the process takes forever.

• If I run run.sh, I will get the error as described even though I have installed the command as you instructed.
• If running on Windows parallels, conversion and training are completely normal (However very slow)

Do NOT use run.sh. venv is NOT conda.

Run python xxxx.py instead.

I successfully reinstalled it on Mac M2 Max according to the instructions, but when I run inference I get the error below and the program automatically crashes.

Python.framework/Versions/3.8/lib/python3.8/multiprocessing/resource_tracker.py:216: UserWarning: resource_tracker: There appear to be 1 leaked semaphore objects to clean up at shutdown warnings.warn('resource_tracker: There appear to be %d '

[Conghdos]

Well I fixed it, just reinstalling faiss-cpu is enough pip install faiss-cpu==1.7.0

[jathoo]

sorry new to this , so i tired to install it using run.sh and got the exact error

tried to fix it with

brew install libxml2 brew install libxslt

and used

pip3 install lxml==4.9.2

then tried to start the app with run.sh and still getting the same error

want to try this but not really sure which file to use as xxx

Run python xxxx.py instead.``` 

could you please explain this ? 

[R3D347HR4Y]

@jathoo run.sh does this command by default but there are some things wrong when running the rest of run.sh in OSX So instead run this: python infer-web.py

[burakaydinofficial]

conda install lxml fixed this issue for me on my M1

[PetervanLunteren]

I was unable to pip install lxml on my macOS M2 PRO, but thanks to the tip provided by @burakaydinofficial, I was able to successfully get it installed using the command below.

conda install lxml
