GPU checkpoint: cannot load incompatible bytecode

[ZahlGraf]

Hi,

I want to try out the eval script and when I use the pretrained GPU checkpoint I get the following error:

th eval.lua -model ../PreTrained/model_id1-501-1448236541.t7 -image_folder ../TestImages -num_images 1

My system is Jetson TX1. Could there be a compatibility issue one different systems?

If I use the CPU checkpoint I get a slightly different error:

th eval.lua -model ../PreTrained/model_id1-501-1448236541.t7_cpu.t7 -gpuid -1 -image_folder ../TestImages -num_images 1
