Cannot use concurrent for multiple statement in non-task mode

[gaow]

Here is a MWE:

[1]
input: [f'{x+1}.txt' for x in range(2)], group_by = 1, concurrent = True
bash: expand = True
 echo {_input}
python: expand = True
 print({_input:r})

Running this script I get a warning:

WARNING: Input groups are executed sequentially because of existence of directives between statements.

and the jobs are not done in parallel. However it seems to me that there should not be any ambiguous logic here that prevents the parallelism. So am I missing something here? What can I do to still achieve concurrent without using task?

It is a bug cause by multiple actions in a step. It should have been fixed.

Great, the MWE was fixed. But I run into this problem:

 File "/home/gaow/Public/miniconda3/lib/python3.6/site-packages/sos-0.9.11.3-py3.6.egg/sos/parser.py", line 693, in __init__
    self._read(fp)
  File "/home/gaow/Public/miniconda3/lib/python3.6/site-packages/sos-0.9.11.3-py3.6.egg/sos/parser.py", line 1211, in _read
    raise parsing_errors
sos.parser.ParsingError: File contains parsing errors: /home/gaow/GIT/github/ipynb-website/release
	[line  4]: 
local variable 'starting' referenced before assignment
	[line  7]:

	[line 74]: 
local variable 'starting' referenced before assignment
	[line 100]: 
local variable 'starting' referenced before assignment
	[line 213]: 
local variable 'starting' referenced before assignment

The problem was obvious from the code but I am not sure enough of intended logic to fix it.

Try again.

I think it works! Will reopen if I later find it otherwise.
