RuntimeError: subprocess returned error: Success

Title: RuntimeError: subprocess returned error: Success

Description:

Hi,

I'm new to osmium and encountered a runtime error while using the library. Here's the code snippet I'm working with:

import osmium

class OSMWayReader(osmium.SimpleHandler):
    def __init__(self, path):
        osmium.SimpleHandler.__init__(self)
        self.street_ways = []
        self.path = path

    def way(self, w):
        # Process ways (implementation omitted for brevity)
        pass

    def read_ways(self):
        self.apply_file(self.path, locations=True, idx='flex_mem')
        return self.street_ways

When calling the read_ways method, I get the following error:

INFO -   File "/nfs/shared/virtualenvs/lib/python3.9/site-packages/search/utils/map/osm_reader.py", line 66, in read_ways
INFO -     self.apply_file(self.path, locations=True, idx='flex_mem')
INFO - RuntimeError: subprocess returned error: Success

I've searched extensively but couldn't find any concrete solution or explanation for this error.

Environment Details:

• Python version: Python 3.9
• Osmium library version: 3.7.0
• Operating system: ubuntu 18
  Any guidance or help on why this error occurs and how to resolve it would be greatly appreciated.

Thank you!

The code snippet works for me. Do you really can see the error, when you omit the code for your way() callback, as in the example above? If yes, then please post the code that calls read_ways(). If there is no error, then the problem is likely in the callback code and we'd need to see that.

Side remark: if you are new to pyosmium, I strongly recommend to get the latest 4.0 version. The new iterative FileProcessors are a lot easier to understand and handle for beginners with the library.

You're right. Apparently the error was caused by some sort of wrong path. Thank you, and I'm sorry for taking your time.
