Depthai: Installation issue when using M1 Chip

[esbasti]

Hi,

Has anyone experienced issues when trying to run python3 install_requirements.py in Big Sur OS.

Seems like the problem is related to the numpy library. However, I was able to install numpy through home brew and did not get the same error.

Happened on Big Sur running on a M1 chip

Here is the error log:

Requirement already satisfied: pip in /opt/homebrew/lib/python3.9/site-packages (20.3.3)

Hi @esbasti ,

I have not seen this. But I do have something that might be helpful. Here is what we did to get development working on M1 Macs:
https://discuss.luxonis.com/d/69-running-depthai-on-apple-m1-based-macs

The why is that some development tools don't yet run natively on M1 Macs.

Thoughts?

Thanks,
Brandon

[esbasti]

Thank you @Luxonis-Brandon for getting back to me.

I tried running the terminal under Rosetta.

But, unfortunately I'm still getting the same error.

[Luxonis-Brandon]

Got it. Just to make sure I'm on the same page, have you already run the following (from here)?
sudo curl -fL http://docs.luxonis.com/_static/install_dependencies.sh | bash

If you haven't please do close and re-open the terminal after doing so, and run python3 -m pip install -U pip, which should show something like:
Requirement already satisfied: pip in /Users/leeroy/Library/Python/3.9/lib/python/site-packages (20.3.3) if it is already updated.

And I want to share this video in case it's helpful in getting up/going:
https://www.youtube.com/watch?v=0RGmmjed3Hc&feature=youtu.be

Unfortunately I don't have an M1 Mac on hand (I really want to get one) to try out, otherwise I could see about reproducing. @alex-luxonis does have one.

[esbasti]

Thanks for the video, it was very helpful

I was skipping the python3 -m pip install depthai

Notheless I get a new error when running this command.

I think this time the error is caused by home brew. I tried to run homebrew under rosetta 2. But, still got the same error

[Luxonis-Brandon]

I saw that one once as well. Can you close the terminal, re-open, and run python3 -m pip install -U pip ? And then try python3 -m pip install depthai again?

[Luxonis-Brandon]

Oh, and sorry. cmake wasn't installed somehow.

Can you do brew install cmake?

[alex-luxonis]

Hi @esbasti,

This doesn't seem good:

Collecting depthai
Using cached depthai-0.4.0.0.tar.gz (84 kB)

It tries to build the wheel from sources (.tar.gz), while a prebuilt wheel should have been used instead. It might be because the command was ran initially natively (not under Rosetta 2).

Could you open a terminal under Rosetta and confirm that the command uname -m returns x86_64. Then try:

python3 -m pip uninstall depthai -y
python3 -m pip install depthai --no-cache-dir

I'm getting this output on Apple M1 with python 3.9.1.5:
Collecting depthai Downloading depthai-0.4.0.0-cp39-cp39-macosx_10_9_x86_64.whl (2.9 MB) |████████████████████████████████| 2.9 MB 2.8 MB/s Installing collected packages: depthai Successfully installed depthai-0.4.0.0

[esbasti]

Hi @alex-luxonis thanks for looking into this as well

I can confirm you that after running the command uname -m returns x86_64

Notheless, when i run python3 -m pip uninstall depthai -y got the following warning

WARNING: Skipping depthai as it is not installed.

And when run python3 -m pip install depthai --no-cache-dir

Here is the error log

[alex-luxonis]

@esbasti Thanks for trying out the commands.

So after I installed Homebrew and then the other packages (python3, etc) under Rosetta, later on even when running in a native arm64 terminal, I still got the prebuilt x86_64 depthai wheel getting downloaded and installed by pip.
I also upgraded to the latest Big Sur (11.1), but all was still fine.

I'm reinstalling macOS now, and trying to see if I could get to reproduce your situation, where the build from sources is always attempted. This will take some time...

Just in case, if you haven't already, could you try closing and reopening terminal consoles and maybe also rebooting. Sometimes changes done by installed programs (altering PATH or other environment variables) don't take effect otherwise.

If still no improvement, could you try the command that Brandon suggested brew install cmake and see if the build from sources gets to work.

[alex-luxonis]

@esbasti So I erased and reinstalled Big Sur on my Mac M1, then did these:

1. Opened Terminal and executed this dependencies install script from our website:
   https://docs.luxonis.com/en/latest/pages/api/#installing-system-dependencies
   sudo curl -fL http://docs.luxonis.com/_static/install_dependencies.sh | bash
   Then ran python3 -m pip install depthai and was greeted with the same situation you encountered: it downloaded the .tar.gz and attempted the wheel build, failing.

2. Opened another Terminal under Rosetta 2:

   • right-click -> Get Info -> ticked Open using Rosetta. Then trying to open it prompted me to install Rosetta, and after that I was able to open it.
   • tried again python3 -m pip install depthai and was prompted with the same situation and error.
   • ran again the dependencies install: sudo curl -fL http://docs.luxonis.com/_static/install_dependencies.sh | bash
   • tried again python3 -m pip install depthai , still with no luck. brew install cmake didn't helped.
   • closed the terminal

3. Opened again Terminal under Rosetta 2:

   • ran python3 -m pip install depthai and at this point it worked as expected, downloading the _x86_64.whl

Next I cloned this repo, ran python3 install_requirements.py, then python3 depthai_demo.py, all working well.

I highlighted in bold the steps from above that I believe helped. Let us know how it goes on your side.

[esbasti]

Still not luck.

Tried the steps above

And after running the command python3 -m pip install depthai I'm still getting the error below

Also thought it may had to do something with how I installed Brew and Rosetta and try this:

https://stackoverflow.com/questions/64963370/error-cannot-install-in-homebrew-on-arm-processor-in-intel-default-prefix-usr

But it still fails

ERROR: Failed building wheel for depthai
Failed to build depthai
ERROR: Could not build wheels for depthai which use PEP 517 and cannot be installed directly

[alex-luxonis]

@esbasti I was able to build the depthai wheel from sources under native arm64, after adding the Homebrew install to PATH manually: export PATH=/opt/homebrew/bin:$PATH. I also had to brew install cmake libusb.

I also see from your logs above that the build was progressing, but reaching some permission issues in ~/.hunter directory. I believe this happens because the command was ran at some point with sudo (sudo python3 -m pip install depthai). Maybe you could resolve the problem by deleting this directory entirely: sudo rm -rf ~/.hunter (should be safe to do that, Hunter is a source-code-level package manager we use for builds).

But anyway, this isn't the right direction for fixing the problem (at least for now), as some python libraries are still not supported under native Apple M1. Most prominent is numpy, that we depend on for depthai. So for now we need to stay with the x86_64 translation, and thus should get the prebuilt to work (and don't even attempt build from sources):
python3 -m pip install --only-binary=:all: --no-cache-dir depthai

To check directly under which platform python3 runs: python3 -c "import platform; print(platform.platform())" :

• macOS-11.1-arm64-i386-64bit - bad, native
• macOS-11.1-x86_64-i386-64bit - OK, with emulation

In your case it must be something with the Homebrew install. Could you check the PATH env var echo $PATH , and if by any chance /opt/homebrew is included, remove it.

And if the problem persists, maybe even remove completely Homebrew, running in a native terminal:

1. /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
   --should remove it from /opt/homebrew
2. arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
   --should remove it from /usr/local

And then reinstall with this command under Rosetta:
sudo curl -fL http://docs.luxonis.com/_static/install_dependencies.sh | bash
followed by closing and reopening the terminal.

[esbasti]

Finally I was able to install all dependencies successfully and run the demo.

What ended up working was what @alex-luxonis suggested. Which was:

And if the problem persists, maybe even remove completely Homebrew, running in a native terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
--should remove it from /opt/homebrew
arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"
--should remove it from /usr/local

And then reinstall with this command under Rosetta:
sudo curl -fL http://docs.luxonis.com/_static/install_dependencies.sh | bash
followed by closing and reopening the terminal.

In addition to running this commands I had to manually delete the Homebrew directory in both locations.

Thank you both for taking the time and troubleshoot for a solution @Luxonis-Brandon @alex-luxonis

[Luxonis-Brandon]

Glad it's working and thanks for circling back!

[alex-luxonis]

Thanks! Closing as resolved.

We also updated the install script for macOS, it can be run now on M1 without having to run the terminal under Rosetta (it will automatically prefix certain commands with arch -x86_64):

[whabilly]

The DepthAI API and examples (gen2_develop branch) run fine natively on M1 by the way, once you get native OpenCV for Python installed (I built it from source weeks ago, but it should be possible to install it now using conda via conda-forge) as well as Numpy (also using conda-forge).

[alex-luxonis]

We were thinking to recommend users to run under Rosetta, until opencv-python, numpy, etc. get to a stable state on M1 arm64, or at least could be built from sources with pip. As the performance under x86_64 translation seems pretty good anyway.
But we could look at conda-forge. Thanks!

[whabilly]

I have been using M1-native only development tools since day 1 (early December) and so far Homebrew and Conda-forge have provided all the packages I needed, and in the worse cases building from sources has not been an issue at all.

[Luxonis-Brandon]

Thanks, both. And good to know @whabilly . The M1 chips are so impressive. Cool to see computer innovation like this. Before the M1, it seemed computer processors weren't -really- getting any faster in terms of daily user experience.
