Bug

First of all, thank you for this package! I am excited to test it out. I have a slight issue, however. I created a fresh environment to test out the package.

When trying to import modules from the maestro package, there's a NumPy version compatibility error. The error suggests that a module compiled with NumPy 1.x is being run with NumPy 2.1.1, which can cause crashes.

Code to reproduce:

from maestro.trainer.common import MeanAveragePrecisionMetric
from maestro.trainer.models.florence_2 import train, TrainingConfiguration

Error message:

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.1.1 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.

Hello @wjbmattingly I was setting up CI and other configuration I decided to take look this problem and

• Tested python 3.12 OSX "worked" ✅ - no problem detected
• Tested python 3.11 OSX "worked" ✅ - no problem detected
• Tested python 3.10 OSX "worked" ✅ - no problem detected
• Tested python 3.9 OSX "worked" ✅ - no problem detected

I assumed mac you used apple silicon and I used brew to install all of the pythons(3.6 to 3.13) all of them tested under new virtualenv envs and no-cache installs

OSX version: Sonama 14.6

@wjbmattingly related PR #43 I worked for ci and package dependencies (I tested on this PR branch)

@wjbmattingly We just merged changes I made so could you please re-try this to verify is it work or not, thank you.

This is so strange. I created a new Conda env and reinstalled. I have the same error for some reason. Here is the full error:

I am in a fresh Conda env with Python 3.10. Perhaps it's an issue with Conda? I can try using virtualenv to see if that helps. All I did to install was the following

pip install --no-cache-dir maestro

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.1.1 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

@wjbmattingly It is looks like a conflict between cv2 and numpy, what I can suggest to you is remove "opencv-python-headless" and use conda version of opencv instead of pypi package, But I am pretty sure it works on normal python installations (I installed all of them via "brew" (brew install python@3.10,brew install python@3.9,brew install python@3.8)

I also mode github action that making sure it works for OSX as well. So I am pretty sure it works fine (but conda has different package source)

[wjbmattingly]

Ok! That did the trick, thanks so much!! (I uninstalled and used the conda version of opencv) I have a few new errors, but I think I can now debug these.

I will work on conda of maestro so hopefully you can install easily, let's keep this issue open but let me change title of issue to "conda related" bug so I can work on this too as well.

Thanks! That works for me. If you want me to do testing when you have this ready, let me know. More than happy to test it out.
