Subject: [Freesurfer] error running samseg on cluster

        External Email - Use Caution        

Hi All,

I am trying to run samseg as follows on a cluster and am getting a message that I need to install tensorflow (which is already installed). Please see below. 
Please advise how to fix this. 

Many thanks

Rito
