Am trying to a transition state optimization problem for the isomerization reaction, cis-HCNH -> trans-HCNH, with no success. psi4 returns : unable to compute torsion value
Optimizer: Optimization failed! (I tried several geometry guesses but none was successful).
Am I doing something wrong? Any suggestions/pointers
Thanks.
Here is the psi4 input
#cis to trans transition state optimization

It seem the conda build is not yet updated to v1.1. Trying to update psi4 in my anaconda environment returns no updates. Is there an alternative way of doing it?
1.1 release series conda packages are “hidden” on a subchannel until release. Issue one of these commands to get a 1.1-era package. Go ahead and create a new conda environment rather than updating or installing into your 1.0 environment.
