Compile error

When I try to compile the image as README instruction, it gives an error of building matter:

Log data follows:

I tried to run the pip3 install numpy and pip2 install numpy on host shell , both commands run successfully.

The target I used is imx6ullevk:

MACHINE ??= 'imx6ullevk'
DISTRO ?= 'fsl-imx-xwayland'

Also, I have tried to set the proxy, and the networking can access the python package site.

How can I fix this problem?

Hi @tonyho ,
Were you able to solve the above issue?
Is it useful for the imx6ull target?
