RockX 1.1.0 ROCKX_MODULE_FACE_RECOGNIZE 失败

大家好,
我安装了 RockX 1.1.0 Python 版本后,在运行人脸识别的官方例程时报错,ROCKX_MODULE_FACE_RECOGNIZE 无法初始化.(其他的例子都可以)运行命令和输出结果:
firefly@firefly:~$ python3 -m rockx.test.camera.rockx_face_recog -b face.db -i /home/firefly/FaceBank
camera= 0
db_file= face.db
image_dir= /home/firefly/FaceBank

请问该如何解决?

It looks fixed by RickX 1.2.0?
