CUDA fails to load

Windows Version

10.0.26200.8037

WSL Version

2.6.3.0, 2.7.0.0

Are you using WSL 1 or WSL 2?

• WSL 2
• WSL 1

Kernel Version

6.6.87.2-1, 6.6.114.1-1

Distro Version

Ubuntu 24.04

Other Software

CUDA 12 as loaded by TensorFlow.
NVIDIA Studio Driver 595.79.

Repro Steps

$ python3 -m venv /tmp/repro/
$ . /tmp/repro/bin/activate
$ pip install 'tensorflow[and-cuda]'
$ LD_DEBUG=libs python3 -c 'import tensorflow as tf; print(tf.config.list_physical_devices("GPU"))' 2> ld_debug.log

Expected Behavior

TensorFlow detects the NVIDIA GPU.

Actual Behavior

It does not, presumably because of these errors:

WslLogs-2026-03-16_21-34-21.zip

Start by reproducing the issue with the listed Python virtual-environment and TensorFlow installation commands, then inspect ld_debug.log and the attached WslLogs archive. Focus on the reported CUDA and libdxcore undefined-symbol errors and compare behavior across the listed WSL, kernel, driver, and Ubuntu versions. Done means TensorFlow detects the NVIDIA GPU without those loader errors.
