Dear Freesurfer team,

 

I have now fs 7.3.2 installed on ubuntu 22.04.2 on a 8 core i7-4790 CPU (supporting AVX instructions)  with 28.0Gb  fs works fine now,  but I had a patient where the segmentation did not work  well, so I wanted to try  mri_synthseg.

I have tensorflow 2.4.1 (python 3.7.13) installed and running on a gtx 1650 gpu. So running mri_synthseg first time did not prompt to install it again.

When I run mri_synthseg  it tells predicting 1/1 and after about 25 sec it terminates telling: „terminate called after throwing an instance of ‚std::bad_alloc‘“  what(): std::bad_alloc  Abort(core dumped)

?????????? (memory problem??)

It terminates independent of using other patients, or gpu – cpu or more or less cores..

I also tried „synthstrip“ to test the tensorflow installation working with fs and this works well!

Do you have an idea, & solution???

Greetings Jürgen
