I installed slicer 5.8.0 and extension of total segmentator .But total segmentator did not work successfully. And total segmentator run successfully in slicer 5.6.2.  
I reinstalled slicer 5.8.0 and extension of total segmentator several times, but problem is still not resolved.  
Could you give me some suggestion to resolve this problem?

error window pops up：

```auto

**Are you using a GPU?**  
If so, could it be that GPU memory is not being released properly or is occupied by another process?

I had a similar issue before, and in my case, an **“out of memory”** error didn’t appear, which made it difficult to figure out the cause. You might want to check if GPU memory is still in use by running:

sh

```auto
nvidia-smi

```

If some process is occupying the memory, try terminating it and then running TotalSegmentator again.

thanks for your reply！  
I use MacBook Air m1,which gpu not available.  
And total segmentation work well in 5.6.2 version of slicer installed in my Macbook for long time.

Since you’re using a **CPU** , this topic might be relevant to your issue:

[How to solve PyTorch version error in TotalSegmentator using CPU](https://discourse.slicer.org/t/how-to-solve-pytorch-version-error-in-totalsegmentator-using-cpu/36269)

It seems that there could be a **PyTorch version compatibility issue** when running TotalSegmentator on CPU. You might want to check if updating or downgrading PyTorch helps resolve the problem.

I check PyTorch module. and PyTorch 2.2.2 already installed ,using cpu.
