Installation and run cryosparc configure initial

Hi specialists,

At the end of installation, I tried to run “./cryosparc configure initial”.
The message came as follows:
[jianhaoc@brain3 bin]$ ./cryosparc configure initial

Traceback (most recent call last):
File “/home/jianhaoc/s/cs2/bin/configure.py”, line 31, in
allenv = trycall([“bash”, “-c”, “source config.sh && env”])
File “/home/jianhaoc/s/cs2/bin/util.py”, line 8, in trycall
ret = subprocess.check_output(cmds, **kwargs)
AttributeError: ‘module’ object has no attribute ‘check_output’

Am I miss something? Thank you in advance!

Regards,
Jianhao
