Hey all. I have a question, and I hope this is the right Slack to ask it in. I am trying to get Molecule to work on Windows 7 to test Ansbile roles. I get everything installed, however, when I try and run Molecule, it tells me that sh 1.12.14 is currently not available on Windows, and to install pbs instead. I used pip install pbs, but now I am not sure how to actually get Molecule to use it instead of sh.

I am trying to understand why the multi-processing code keeps waiting. My code works completely fine standalone. Here is the dumbed down version (does not compile) : ``` import someLib
##someLib library has both Request and process modules
def delegate(response, unwm_img_path, wm_url):
'''
do something here
'''
def worker(image_url):
print(image_url)
start = time.time()
i = 0
req.image_path = get_path(image_url)
print('before: ', req.image_path)
new_rows = delegate(someLib.process(req), req.image_path, image_url)
print('after: ', req.image_path)
if new_rows is not None:
print(new_rows)
else:
print('not processing ', image_url)
else:
print('failed to open image:', image_url)
if __name__ == '__main__':
with open(file_path, 'r') as f:
image_urls = sum(list(csv.reader(f)), [])
if os.path.exists(cf_file_path):
append_write = 'a' # append if already exists
else:
append_write = 'w' # make a new file if not
1_file = open(cfile_path, append_write)

wr2 = csv.writer(afile)
req = someLib.Request()
pool = Pool()
pool.map(worker, image_urls)

Best explained with an example probably:
`f(seq=range(8), grouping_function=lambda x: x % 3) == [[0,3,6]. [1,4,7], [2,5]]`

Perhaps there's a nicer way to solve my problem though: I want to grab the first value in each group created by splitting a sequence up using some function.
Right now I'm thinking of doing something like
```
for k, group in groupby(sorted(seq), partitionfunc):
yield next(group)
continue
