导入numpy，错误

lxkjcn

try:
from ulab import numpy
except ImportError:
import numpy

运行提示：ImportError: no module named ‘numpy’
固件包含ulab

你是吃太饱了吗？

要用array运算

lxkjcn

img = sensor.snapshot()
a = np.array(img, dtype=np.uint8)
提示：ValueError: first argument must be an iterable
怎么解决？

然后看看固件里有没有 ulab 包吧，正常情况下是没有的

有ulab，第5行
