Unable to install Speckle-QGIS on M1 Mac

Unable to load the Speckle plugin on QGIS for Mac

I’ve tried to load the Speckle 2.0 Connector for QGIS using the QGIS plugin manager window. The plugin was installed successfully but its toolbar didn’t load. I also have tried to reinstall and install from the zip file. When I relaunch QGIS a error message appears with the following Unable to load plugin ‘speckle-qgis’ due to a error when calling Class Factory(). AttributeError: module ‘speckle-qgis’ has no attribute ‘classFactory’ Traceback (most recent call last): File “/Applications/QGIS…

I’m running into a very similar issue today trying to get the QGIS connector to install on MacOS Monterey 12.6. The plugin seems to install correctly, but the Speckle icon doesn’t appear. After restarting QGIS, I see the following error on launch.

My setup:

• Macbook Pro M1
• MacOS 12.6
• QGIS 3.28.3 (Firenze)
• Speckle QGIS connector 2.13.0

Here’s the error log I see when I open QGIS after install through the official plugin manager:

Couldn't load plugin 'speckle-qgis' due to an error when calling its classFactory() method

I’ve also tried uninstalling the plugin manually and installing it directly by cloning the main branch from Git. This raised another error related to pip being unable to install the dependencies automatically.

Any suggestions for me?

[jonathon]

Thanks for the report. We’re investigating issues with M1 Mac support for the 2.14 release. So far these appear to be where C based dependency packages or even sub-dependencies aren’t being released built to address the M1.

I have 2.13 already installed and running on my test M1 MacBook, (both from QGIS plugin Manager and from source) so I’ll look into your error log if urllib3 or any of its requirements being drawn on install are different (potentially newer)

The installing from source (GitHub) issue you encountered is similar. We may need to be extremely granular in specifying and pinning requirements.

[nate_peters]

Thanks Jonathon. Happy to test any pre-release fixes you guys come up with. I’ve also been messing around with my local installation of Python this week (I moved from Anaconda to Homebrew-installed Python 3) and I was thinking that may be an issue, but it looks like QGIS only tries to access a copy of Python 3.9 that it installs itself?

[gergo (Gergő Jedlicska)]

Hey @nate_peters you are correct, QGIS like almost all other app utilizing python somehow tends to vendor a specific python version with the app, to avoid missing python, version mismatch or any other platform / host OS related issues. So you can mess around with your python installations as much as you want, you are (most probably) not gonna break QGIS

We have to do our best to target the python binaries included in the applications. And we have to make sure all of the dependencies we rely on support all the platforms that we support. Recently this has been getting better, but the Apple transition to ARM (M1) really made this tricky, cause python packages bundling compiled binaries had to supply an M1 compatible build.

In our current case unfortunately we’ve included a dependency, that is not yet updated to target the Apple ARM platform. We’re looking for a good solution on this.

[Kateryna]

Hi @nate_peters , please try the latest release (2.14.1), this hopefully resolves the error. Let us know!

[nate_peters]

Still seeing an error sadly - this is what I’m seeing after installing 2.14.1 and restarting QGIS. It appears to be the same error.

I’m seeing a second error from QGIS related to Python after the Speckle error too. I’ve been looking for a solution to this but haven’t had any luck yet. I was seeing this sporadically before installing the Speckle plugin so I don’t think it’s directly related to the plugin itself, and Python itself inside of QGIS appears to work fine. Just wanted to add this for context in case it’s relevant.

An error has occurred while executing Python code:

@nate_peters

/Applications/QGIS.app/Contents/MacOS/lib/python3.9/site-packages/

Thanks for checking! Could you please look into the folder /Applications/QGIS.app/Contents/MacOS/lib/python3.9/site-packages/ and tell the versions of the packages requests_toolbelt and urllib3?
e.g. 0.10.1 and 1.26.16

[nate_peters]

requests_toolbelt: 0.10.1
urllib3: 2.0.2

[Kateryna]

Thanks!
Now, check if the folder /Users/nate/.config/Speckle/connector_installations/QGIS also has urllib3 folders, if so, delete them both, and in QGIS → Plugins → Python Console paste this:

path = r"/Users/nate/.config/Speckle/connector_installations/QGIS"

#find executable on Mac
pythonExec = os.path.dirname(sys.executable) + "/bin/python3"

# installing the library
import os; import sys; import subprocess; result = subprocess.run([pythonExec, "-m", "pip", "install", "-t", path, "urllib3>=1.26.0,<=1.26.16"], capture_output=True, text=True, shell=True, timeout=1000); print(result) 

Let’s see what the output is and if the folders for urllib3 have re-appeared in /Users/nate/.config/Speckle/connector_installations/QGIS, and in which version

P.S. if the urllib3 has been now installed to this folder with the correct (1.26.x) version, you should be able to start the plugin with no issues after restarting QGIS.

I checked in the .config folder you mentioned, and urllib3 version 1.26.16 was installed there. I removed it and then moved on to the Python step. The script didn’t return anything useful. Am I running this in the right place? It doesn’t appear that the logs from the subprocess made it up to the QGIS console.

Here’s the text output in the console:

exec(Path('/var/folders/tb/mbxx86bj0g366_nkxh63m6t80000gn/T/tmp6hnndayu.py').read_text())
CompletedProcess(args=['/Applications/QGIS.app/Contents/MacOS/bin/python3', '-m', 'pip', 'install', '-t', '/Users/nate/.config/Speckle/connector_installations/QGIS', 'urllib3>=1.26.0,<=1.26.16'], returncode=0, stdout='', stderr='')

Thanks a lot @nate_peters ! The console returned code ‘0’, which is good news, and it’s not another Mac M1 issue not installing specific library versions, that I was worried about

But there appears to be 2 problems.

• Some of the essential Python libraries turned out incompatible in the latest release, and you have installed a very-very fresh version of all the packages recently (which is why you are the first one to get this error)

Speckle plugin for QGIS creates it’s own folder with all dependencies, and imports them from this folder, but here’s the issue #2:

• It seems that some of the libraries are imported into QGIS before Speckle plugin loads, so it picks up the installation from the default Python setup rather than the new custom folder. This is why the required urllib-1.26.16 is being ignored and 2.0.2 picked from the default Python instead.

We need to investigate this issue better, because more users might start having this issue soon But the quick solution for you would be to pip install urllib3 version 1.26.16 to the default python libraries ( /Applications/QGIS.app/Contents/MacOS/lib/python3.9/site-packages/), of course, if you don’t need the 2.0.2 in your other applications.

Hope this helps!
