Importing PyTorch Causes Large Image to Silently Fail To Open Tile Sources

[amrosado]

Importing pytorch then importing large_image causes large_image.open to fail silently

Python 3.14 and 3.13
PyTorch: 2.10.0+cu130
Large image: locally built from commit 7024fc6 and pip release 1.34.0

Minimal reproduction:

import os

import torch

import large_image

source = large_image.open('any_file.svs')
print(source)

This is a major blocking issue for me.

Hmm.... I don't have the issue with PyTorch 2.7.0+cu128. If you import in the opposite order what happens?

[manthey]

I should have also asked what OS are you using.

And, I also don't see this on PyTorch 2.10.0+cu130, Python 3.14, Ubuntu 24.04.

If I alter the order and import large_image first it works:

import os

import large_image

import torch

source = large_image.open('/wsi_archive/APOLLO_NP/2000/OS00-01/OS00-01_H&E_6.svs')
print(source)
