metaclass conflict: the metaclass of a derived class must be a (non-strict) subclass of the metaclasses of all its bases

[Tie-1]

hi @yuqingd ,thanks for your public work! When i run

CUDA_VISIBLE_DEVICES=0 python train.py --gpudevice 0 --id S3000 --outer_loop_version 3 --dr --train_sim_param_every 1 --prop_alpha --update_sim_param_from both --alpha 0.1 --mean_scale 1.75 --train_range_scale .5 --domain_name dmc_ball_in_cup --task_name catch --range_scale .5 --scale_large_and_small --dr_option simple_dr --save_tb --use_img --seed 1 --num_train_steps 1000000 --encoder_feature_dim 64 --prop_range_scale --prop_train_range_scale --separate_trunks --num_sim_param_updates 3 --save_video --eval_freq 2000 --num_eval_episodes 3 --save_model --save_buffer

some errors happend:
