Some errors when testing Fluid on minist tuning

[xyzustc]

I am trying to writing code tuning minist to observe the performance boots provided by Fluid, but got some errors.

My env

A 8-gpus local server. Python 3.7.11. ray 0.8.5.
Not using pip package, but using Fluid implementation from the newest repo, aka. the repo after this commit:

commit bc59400c61da7e6fde3cac29ddfe40a718795a58
Author: Peifeng Yu <[email protected]>
Date:   Fri Jan 7 19:55:44 2022 -0500

    Log for debugging CI

RUN and ERROR info

I am in Fluid/workloads now. I run cp -r ../fluid ./rfluid to avoid ambiguity when importing.
I run this tune_fluid_minist.py use python tune_fluid_minist.py -l
(This tune_fluid_minist.py file is based on Fluid/workloads/tune_fluid_minist.py of this repo, but change the import and change the Executor used.)

I got error like this : all_error_output_info.txt
I take the Traceback parts in the output here:

VERY thanks for you reply !
I am also trying understand these errors.
