resolve this error

[MatthiasWilm]

I am a novel user of Spades. I solved the error by modifying a python script:
Operation Environment
SPAdes version: 3.15.3
Python version: 3.10.1
OS: macOS-12.1-x86_64-i386-64bit

Edited file: ... /share/spades/pyyaml3/constructor.py
Line: line 126
Code was: if not isinstance(key, collections.Hashable):

Code is: if not isinstance(key, collections.abc.Hashable):

Reference Source:
https://docs.python.org/3/library/collections.abc.html
"New in version 3.3: Formerly, this module was part of the collections module.
...
This module provides abstract base classes that can be used to test whether a class provides a particular interface; for example, whether it is hashable or whether it is a mapping."

No need to modify anything. The fix is included into the latest SPAdes 3.15.4 release

[CalJMarsh]

Hi asl,
I am trying to use spades on mac, installing with bioconda. The latest SPAdes version available for mac osx is the 3.15.2 release. I am experiencing the same attribute error when I try to test my installation of SPAdes.
Do you know if this fix will be available for Mac? the constructor.py script is different to the version listed in the fix above.

[asl]

@CalJMarsh As it was stated above, the fix is included in SPAdes 3.15.4 release. On all platforms Mac included. Check SPAdes manual (https://cab.spbu.ru/files/release3.15.4/manual.html#sec2) for installation guide

[dhiru16]

I got the same error but am using the spades 3.15.5

@dhiru16 Will you please open a new issue attaching all the files requested?
