小白初次接触TB-RK3399Pro开发板，运行上边的表情识别案例时遇到以下问题：
1、运行python3 rknn_image_demo.py test_images/1.jpg 时，出现以下提示：
File “rknn_image_demo.py”, line 59, in <module>
image_path = sys.argv[1]
IndexError: list index out of range

2、开发板运行python3 rknn_video_demo.py 可以在正常跑通，但是在电脑虚拟机的Ubuntu上ssh远程开发板运行python3 rknn_video_demo.py 出现以下提示:
qt.qpa.screen: QXcbConnection: Could not connect to display
Could not connect to any X display.
求大神解答。

1. rknn_image_demo.py 后面需要加一个图片路径的参数
2. SSH远程运行需安装支持Xserver的客户端软件

可能是keras的版本不对导致无效接口定义，可试试降低TensorFlow的版本?

tensorflow版本是1.11.0版本，执行python3 rknn_transfer.py后总是提醒：ModuleNotFoundError: No module named 'tensorflow.keras.layers.experimental'，怎么解决？系统提醒安装tensorflow2.2版本的，但安装不了，怎么解决？

运行python3 rknn_transfer.py报错如下( python3==3.6.9 , tensorflow==1.14.0, keras==2.2.5), 帮忙看下什么原因

你好，请问TensorFlow的版本和keras的版本分别应该多少呢？既然是官方推荐的帖子，希望能描述详细一些帮到我们
我现在用的是官方1.4.0的docker，rknn-toolkit2-1.40，TensorFlow和Keras 两个版本都是 2.6.2 ，但转换模型时提示：
