NotImplementedError: cannot instantiate 'PosixPath' on your system #341

Closed sshlien closed 4 years ago

sshlien commented 5 years ago

while attempting sixEight = corpus.search('6/8') PosixPath.txt

blueCat11 commented 5 years ago

I get the same error. This works: metadata.bundles.MetadataBundle('core')

but then this throws the error: metadata.bundles.MetadataBundle('core').read()

We are currently trying to rebuild the Cache using http://web.mit.edu/music21/doc/moduleReference/moduleCorpusCorpora.html?highlight=rebuild#music21.corpus.corpora.Corpus.rebuildMetadataCache

Looks to me as if the Posix version is being deserialised and windows dies on that...

By the way, I am running Python 3.7.1 on Windows 10.

This could be an issue with newer versions of Python.

Hello Myke Cuthbert,

For your information, I am still working on some graphic user interfaces for music21 using tkinter. I have attached my latest program still in progress. Progress is somewhat slow since I am still getting used to Python, object coding, tkinter, and music21. I am also working on Humdrum which is written in C++.

I tried this method as well. First, I deleted core.p.gz file in \music21\corpus_metadataCache folder. Then I used rebuildMetadataCache() . It took over an hour, but now I can use the core-corpus on Windows.

Thanks @Lutzifer !

Lutzifer commented 5 years ago

@mscuthbert Maybe it would be a workaround to include two prebuilt metadata files, one for windows and one for posix systems and use them depending on the OS type?

LLight commented 4 years ago

I am running into the same problem, using Python 3.7 on Windows 10 (see the attached code and error message). When I use the corpus.search function, I am getting the same metadata error related to the PosixPath. corpus_search_err.txt

mscuthbert commented 4 years ago

I think that I've fixed this in #459 -- can someone on Windows test this on the latest git? If so, I'll backport release a new v.5 version as well.
