 Wahid Khan | might take a while tho
magma> [1247/3492] Building CUDA object CMakeFiles/magma.dir/magmablas/ctranspose_conj_inplace.cu.o | 13:39:43 |
 Pratham Patel | Share its output please | 13:39:47 |
| Wahid Khan | these 9 derivations will be built:
/nix/store/axpxjk65v92dg8fd89pbj60hkv4v1qzq-magma-2.9.0.drv

| Pratham Patel | What does PAGER= nix-store --query --outputs /nix/store/axpxjk65v92dg8fd89pbj60hkv4v1qzq-magma-2.9.0.drv show? | 13:42:16 |
| Wahid Khan | /nix/store/jsf4ks2kqw05n46zil6qgka27zbh1d6b-magma-2.9.0
/nix/store/ylzb5fvjs1sn7qr4rpjmjpw0ksvf8b0x-magma-2.9.0-test | 13:42:40 |
| Pratham Patel | now test if it is really cached or not nix path-info --refresh --store $FloxCache /nix/store/jsf4ks2kqw05n46zil6qgka27zbh1d6b-magma-2.9.0 | 13:44:25 |
| Wahid Khan | is $FloxCache supposed to be in my env? bc it isnt | 13:44:58 |
| Pratham Patel | nix config show | grep substituter | grep flox | 13:45:20 |
| Wahid Khan | yeah thats as expected it shows cache.flox.org | 13:45:40 |
| Wahid Khan | .dev | 13:45:54 |
| Wahid Khan | * | 13:45:55 |
| Wahid Khan | substituters = https://cache.flox.dev https://cache.nixos.org/ | 13:46:03 |
| Pratham Patel | cache.flox.dev is $FloxCache | 13:46:06 |
| Wahid Khan | alright so i'll do that in path-info args then | 13:46:23 |
| Wahid Khan | 
Download image.png | 13:47:07 |
| Pratham Patel | yeah, not cached | 13:47:17 |
| Wahid Khan | rip | 13:47:22 |
| Pratham Patel | a --refresh didn't fix it | 13:47:29 |
| Pratham Patel | ^ | 13:47:39 |
| Wahid Khan | hmm okay | 13:47:46 |
| Wahid Khan | if it fails to build for wtv reason | 13:47:53 |
| Wahid Khan | i'll try overriding torch with torch-bin | 13:48:01 |
| Wahid Khan | thanks for the help man, learnt a lot | 13:49:52 |
| Wahid Khan | it built magma then proceeded to build onnxruntime and torch from source lol | 15:48:23 |
| Wahid Khan | even with max jobs set to 1 my session died | 15:48:39 |
 Gaétan Lepage | magma is one of torch's dependencies.

It will significantly speed-up compilation compared to targeting the default ones.
