Seer 2.8.0 plays non-sense #189

Hi Connor,

i tried the latest 2.8.0 of Seer on my Win10 machine (i7 with AVX512). No matter what binary a try, the engine plays random moves. The score output only display "info .. score 0.00 ..."

This did not happen in a previous version. If I remember correctly I used 2.6 before and there things worked fine.

Any idea?

Regards Achim

Hello Achim,

Could you check your configured UCI options and validate that all the UCI options are set to the default values? Between Seer 2.6.0 and Seer 2.8.0, an additional QuantizedWeights UCI option was introduced which defaults to EMBEDDED whilst the old Weights UCI option now defaults to UNUSED as only the QuantizedWeights are embedded in the binary. My suspicion is that you've not updated the UCI option configuration when updating from 2.6.0.

Thanks for your interest, Connor
