M1 Mac Instructions Needed

[slabzzz]

Are there any detailed instructions on how to install this for an M1 mac?

[finn200102]

For me worked:

1. Install miniconda
   For miniconda: https://docs.conda.io/en/latest/miniconda.html
   Instructions: https://conda.io/projects/conda/en/stable/user-guide/install/macos.html

2. create an env with python
   conda create -n pix2tex python=3.8

3. Open the env and install the pix2tex package
   conda activate pix2tex
pip install pix2tex

4. Run pix2tex
   pix2tex latexocr

5. Screenshot an image (Shift+Command+4) and copy it (click on the pop up, now click on the image and then click on copy or use any other method to copy the image to clipboard)

6. Now press enter and you should get the LaTeX code

I got to step 4 until getting this error:

RuntimeError: Failed to import transformers.tokenization_utils_fast because of the following error (look up to see its traceback):
dlopen(/Users/xxx/miniconda3/envs/pix2tex/lib/python3.8/site-packages/tokenizers/tokenizers.cpython-38-darwin.so, 0x0002): tried: '/Users/xxx/miniconda3/envs/pix2tex/lib/python3.8/site-packages/tokenizers/tokenizers.cpython-38-darwin.so' (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e)))

[finn200102]

Can you post the packages in your environment?
conda activate pix2tex
conda list

This error means that the "wrong" tokenizer package is installed, m1 is arm based and the package is x86_64 based. The problem seems to be that the packages were installed for the wrong architecture.

Which miniconda did you install, there is a x86_64 and a m1 version? I am not totally sure if the x86_64 version would run, but it could be that through rosetta this version also runs and maybe then x_86_64 packages will be installed instead of the arm ones. Just run:
conda info
And see if platform : osx-arm64 or not.

If it ist x86_64 then deinstall miniconda and install the arm version, then it should work with the steps from above.

At the moment I am using miniforge instead of minicoda, but if they are the arm versions it should not matter, some weeks ago I got latexocr to run on "normal" miniconda.

If all this still does not work, then you could try to follow those steps:
https://www.mrdbourke.com/setup-apple-m1-pro-and-m1-max-for-machine-learning-and-data-science/

This is the exact setup I use at the moment to use machine learning on my m1 and it runs with that setup with the steps from above, but it should work with the arm miniconda version.

I also run into problems with installing the right packages for the m1 and sometimes I get errors that I can only resolve through completely removing miniconda/miniforge and reinstalling them with this method.

My steps on M1:

1. pip install "pix2tex[gui]" the module
2. brew install pyqt@5 the GUI dependency
3. sudo cp -r /opt/homebrew/Cellar/pyqt@5/5.15.7_2/lib/python3.9/site-packages/* /Users/rey/miniconda3/lib/python3.9/site-packages/ * since you cannot find a compatible version on the official forge of pip or conda
4. pip install pynput screeninfo required by the package
5. conda install pytorch torchvision conda will try to install a better version of pytorch on arm 64
