AttributeError: module 'causal' has no attribute '_causal' about causal_learning_unknown_interventions HOT 5 CLOSED

@ronikobrosly I am the author of the C chunk.

1. It must be compiled, a step carried out by setup.py. I suspect you may not have done pip install -e ..
2. It very heavily uses AVX2 and FMA vector extensions, available only on CPUs Intel Haswell/AMD Excavator and newer. A runtime CPU detection code rejects loading the module on CPUs that are too old. I don't see the warning it prints in your error message, so I really suspect you're still at problem 1), but I may be mistaken.

Thank you for the heads up @obilaniu ! I will try this later today and report back here.

Hi @obilaniu , unfortunately that did not seem to work. I ran both pip install -e . and python setup.py develop. When I run
python run.py train --seed 1 --train_functional 10000 --mopt adam:5e-2,0.9 --gopt adam:5e-3,0.1 -v 500 --lsparse 0.1 --bs 256 --ldag 0.5 --predict 100 --temperature 1 --limit-samples 500 -N 2 -p confounder3
I still get AttributeError: module 'causal' has no attribute '_causal'.

Do you have any more ideas?

from causal_learning_unknown_interventions.

@ronikobrosly Well, I'll guess based on your paths that you're on macOS.

I never developed for that platform specifically, and because Apple does things differently I had to disable my CPU check for too-old compilers. My vector code will also 100% not work on very new M1 chips because they're not x86_64 architecture but Aarch64.

Assuming you're still on one of the Intel-based Macs, I propose you remove the try-except from around the import here and say what error message it gives, and furthermore check whether there is a newly-compiled library causal/_causal*.{so|dylib} (or something like that). If there is not, I'd suggest you try pip install -v -e . to see more verbosely what's going on.

I would not be surprised to learn that it failed to compile (x86_64 code will not compile on Aarch64), or fails to import with a failing CPU check (x86_64 CPU is too old).

Ahhh, welp you basically guessed it, Im using a new Macbook Pro with the M1 chip. Oh well, thanks for your help though!
