RuntimeError: CUDA driver error: invalid argument

[Bellakira7]

When I run it internally on my company's machine, which does not have a GPU, this error occurs. I wonder if the problem is with the installation. How should I install it correctly?

CUDA driver errors are frustrating! At RevolutionAI (https://revolutionai.io) we debug these often.

Common fixes:

1. Driver version mismatch:

nvidia-smi  # Check driver version
nvcc --version  # Check CUDA toolkit

2. Environment cleanup:

export CUDA_VISIBLE_DEVICES=0,1,2,3
unset CUDA_LAUNCH_BLOCKING

3. Memory issues:

import torch
torch.cuda.empty_cache()
torch.cuda.reset_peak_memory_stats()

4. ColossalAI specific:

# Ensure proper initialization
import colossalai
colossalai.launch(
    config={},
    rank=0,
    world_size=1,
    host="localhost",
    port=29500
)

Debug steps:

• Run with CUDA_LAUNCH_BLOCKING=1
• Check GPU memory with nvidia-smi -l 1
• Try single GPU first

What GPU and driver version?
