iMX8 bitbake error -AttributeError: Can't pickle local object 'Context.__init__.<locals>.node_class'

[kenjiyamamura]

I am trying to follow the i.MX yocto project user guide to build image for i.mx8 mini evk .

However when I run bitbake command I get the following error :

All Yocto host packages will be installed.
The build was successful before the error occurred.

ubuntu uses 16.04.

python3 uses python3.6.0.
PIP uses 20.0.2.

Below are contents of build.log :

what ubuntu version do you use? did you install all of Host packages as yocto user guide mentions?

[kenjiyamamura]

Thank you for your reply.

All Yocto host packages will be installed.
The build was successful before the error occurred.

ubuntu uses 16.04.

[joanxie]

did you build 4.9.88-2.1.0_8mm_alpha? I suggested that you use the official version from nxp website we have been tested on imx8MM:

Embedded Linux for i.MX Applications Processors | NXP 

suggest to use the latest version 4.19.35 or 4.14.98

[kenjiyamamura]

Thank you for your reply.
4.9.88-2.1.0_8mm_alpha has been built.
Let's build with the official version.
