Errors when converting i3d pre-trained on Kinetics 600

[ZhouKanglei]

When I convert the pre-trained i3d on Kinetics 600, the error occurs as follows:

Key RGB/inception_i3d/Conv3d_1a_7x7/batch_norm/beta not found in checkpoint
         [[node save/RestoreV2 (defined at i3d_tf_to_pt.py:66)  = RestoreV2[dtypes=[DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, ..., DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT, DT_FLOAT], _device="/job:localhost/replica:0/task:0/device:CPU:0"](_arg_save/Const_0_0, save/RestoreV2/tensor_names, save/RestoreV2/shape_and_slices)]]
