Question

数据文件：pattern1.ktx

import numpy as np

data = np.fromfile('pattern1.ktx', dtype=np.byte)

print ('endianness:', hex(data[12:13]))

结果： TypeError：只能将整数标量数组转换为标量索引

看起来够简单吗？我不明白。如何解决这个问题？谢谢。

这个怎么样？

    b = np.frombuffer(np.array(data[12:12+4], dtype=np.byte), dtype=np.uint32)
    print ('endianess:', hex(b))

相同错误。如何解决？

好的，由于某种原因它会返回一个列表，因此必须对其进行索引。

const [alpha, setAlpha] = React.useState(0.0)
const [devicePosition, setDevicePosition] = React.useState({
  centerX: 0.0,
  centerY: 0.0,
  deviceX1: 0.0,
  deviceY1: 0.0,
  deviceX2: 0.0,
  deviceY2: 0.0,
})
const [timer, setTimer] = React.useState(null)

let isMounted = true
React.useEffect(() => {
    const handleOrientation = e => setAlpha(e.alpha)
    window.addEventListener("deviceorientation", handleOrientation, true)
    updateDevicePosition() //make rest call on mounting

    return () => {
        window.removeEventListener("deviceorientation", handleOrientation)
        isMounted = false
    }
}, [])

async function updateDevicePosition() {
    try {
        const result = await fetch("http://192.168.10.233:34599/")
        const data = await result.json()
        if (isMounted) { //so you aren't setting state on an unmounted component
          setDevicePosition({
            centerX: data[0].x,
            centerY: data[0].y,
            deviceX1: data[1].x,
            deviceY1: data[1].y,
            deviceX2: data[2].x,
            deviceY2: data[2].y,
          })
       }
    } catch (e) {
        console.error(e)
    }
    if (isMounted) {
      clearTimeout(timer)
      setTimer(setTimeout(updateDevicePosition, 200))
    }
}

已修复错误。
