Hi, I have been facing this issue, i got the model trained but after that i am facing this.
CUDA_VISIBLE_DEVICES="$GPU" python fit.py --conf confs/train_person_1.conf \

--batch_size 1 --train_rotation True --fixed_images True \
--save_path $DATA_PATH/flame_fitting/$EXP_NAME_1/stage_1 \
--data_path $DATA_PATH \
--fitted_camera_path $EXP_PATH_1/cameras/30000_matrices.pkl
