'pip install mlx' does not seem to work correctly about mlx HOT 49 CLOSED

To summarize on how to install MLX currently using the PyPI packages:

• You need a machine with an M-series chip
• OS >= 13.0
• Python between 3.8-3.11

If you meet those requirements and it still doesn't work, make sure you are using a native python. The output of:
python -c "import platform; print(platform.processor())" should be arm.

from mlx.

My problem is fixed. I was running iTerm on rosetta and Homebrew and all the installed packages (including python versions) were all i386 versions. I now switched completely to arm builds and pip install mlx installs correctly and imports just fine. Thank you all :)

from mlx.

python -c "import platform; print(platform.processor())"

This seems like something that should be mentioned in the readme/docs in BOLD.
I didn't use a native Python, but the following worked for me:

CONDA_SUBDIR=osx-arm64 conda create -n AppleMLX python=3.11

from mlx.

I am having the same issue on a Macbook Air 2020 M1 with a fresh python 3.11 virtual environment.
pip only downloads v.0.0.0 of mlx.

tried the following commands after upgrading pip as pip install --upgrade pip (not in this order):
pip install mlx
pip --force-reinstall --no-cache-dir --upgrade mlx
pip install mlx==0.0.3

all of the above commands somehow downloads the v0.0.0.

It looks like we don't have a wheel for python 12. So for now you can do:

conda create -n myenv python=3.11
conda activate myenv
pip install mlx

We will add a wheel for python 12 ASAP

Can you also try using pip3 install mlx or python3.10 -m pip install mlx and let me know if that helps ?

Nope still getting the same error

from mlx.

I was hitting this and then realized it was because my pyenv/python/pip were all running under rosetta. You can check this with:

python -c "import platform; print(platform.processor())"

If you get back arm it's the non-rosetta version. If you get back i386 it is and you will have to use a non-rosetta python/pip.

If you're in deep with pyenv and pyenv-virtualenv I recommend setting a new PYENV_ROOT for your non-rosetta python versions and venvs and then re-evalling the pyenv init and pyenv virtualenv-inits.

from mlx.

I did but that doesn't seem to work either

Your solution works for me. Thanks!

This seems to have worked for me python3.10 -m pip install mlx, installed the right package.

As I learned, the problem on my side in OSX version, I'm still on Big Sur, but you have build only for 13.x and 14.x.

from mlx.

@oliverks your OS is below the supported versions. Your best bet is to update to macOS 13 or 14.

from mlx.

The install docs are updated to include the issues brought up in this thread. I am going to close this for now, but feel free to reopen if there are new issues with installation.

from mlx.

Hmm very weird, it looks like it might have been a problem with VSCode. I was importing mlx on a jupyter notebook in VSCode and I was getting the above error I mentioned. I moved out of VSCode, and opened a notebook with the conda environment I initially created with an arm arch. I was able to successfully import mlx and I was even able to import mlx using Python in the terminal so it seems like a VSCode issue.

Update: I got it to work on VSCode by following @awni your steps to create a fresh env, thanks for the help :)

from mlx.

I found an easy fix to this issue:

if you see i386 when you run this command: python3 -c "import platform; print(platform.processor())"

Just Download & install macOS 64-bit universal2 installer

Once done, you should see arm now when you rerun: python3 -c "import platform; print(platform.processor())

Now try pip install mlx , it should work.

from mlx.

I use conda install -c conda-forge mlx , it work.

from mlx.

I am finding the same issue. init.py is print("HELLO WORLD").

from mlx.

Can you try installing the latest version of mlx (pip install -U mlx) and let me know if the problem still persists ?

from mlx.

What was the result of running pip install -U mlx ? Maybe we can try forcing pip install -U mlx==0.0.3 instead ?
Also, can I ask what MacOS version you are using ?

Hmm, that's odd
mlx==0.0.0 is an invalid distribution and pypi has the correct mlx==0.0.2 and mlx==0.0.3 for macOS 14

pip install --upgrade pip

Building from source requires that you have a working Xcode installation which provides the metal and metallib utilities - could it be possible that that is missing ?

What is the output from running xcode-select -p ?

Hi!

I have the same problem with python installed using pyenv toolkit.

I'm having the exact same problem in a newly created condo env.

Update: I have succeeded in installing it and runing the stable diffusion example with the Mac system python.

Can you also try using pip3 install mlx or python3.10 -m pip install mlx and let me know if that helps ?

from mlx.

@NilayGaitonde could you run:

pip debug --verbose

It should show you what pip thinks your machine is compatible with. We're looking for something like:

cp310-cp310-macosx_13_0_arm64

from mlx.

When I run that command I get a bunch of

co3x

where x is between 2 and 8, and I see no mention of arm in any of the outputs.

from mlx.

OK great, that was a duh moment, my version was still x86. So I used python3.11 natively which is arm. I now see

cp311-cp311-macosx_12_0_arm64

on the version, but it can't find mlx. I get

(enc) (base) MacBook-Pro-4:mlx oliverks$ pip install mlx
ERROR: Could not find a version that satisfies the requirement mlx (from versions: none)
ERROR: No matching distribution found for mlx

from mlx.

Hey!! yes the problem was fixed thank you! I guess I had the wrong conda architecture on my mac and so was getting i386 on running python -c "import platform; print(platform.processor())" on switching it back to arm I was able to download the correct package. Thank you for your help!!

from mlx.

Alternatively, including the xcode-select path also helps with this issue.

from mlx.

I'm currently running into this error when I'm trying to import mlx:

import mlx.core as mx

ImportError: dlopen(/Users/you/opt/anaconda3/envs/native/lib/python3.12/site-packages/mlx/core.cpython-312-darwin.so, 0x0002): tried: '/Users/you/opt/anaconda3/envs/native/lib/python3.12/site-packages/mlx/core.cpython-312-darwin.so' (mach-o file, but is an incompatible architecture (have 'arm64', need 'x86_64'))

I followed the directions above and created a conda env using the arm arch. I followed the directions from this post. For some context, I'm running:

Python version: 3.12.0
Pip version: 23.3.2
Macbook Pro M1 2020 with 8GB memory running Sonoma 14.2.1

from mlx.

Not sure what's going on there. It looks like your environment might be a bit wonky though.

I would try making a fresh conda environment. Make sure the below gives arm

python -c "import platform; print(platform.processor())"

Then python -m pip install mlx

Let me know if you figure out the problem and what it ended up being!

Unfortunately not. Apple silicon is the primary focus. You could probably get things working on linux without much difficulty building from source. But beyond that, we are not supporting other platforms for the time being.

Did you check this issue #200 ? Most likely you are running python via rosetta for x86:

python -c "import platform; print(platform.processor())"

Should print arm.
