人脸检测上传图片VKSession.detectFace总是无法触发updateAnchors回调？
init() {

console.log('%c =======>anchors', 'color: #6fc1ff; font-weight: bold', anchors)
})
// VKSession removeAnchors
// 识别目标丢失时不断触发
session.on('removeAnchors', anchors => {
that.tipsText = '检测不到人';
that.photoDisabled = true
});
try {
session.start(err => {
