Issues reading SPC file contents into Dash App with scp.read_spc(content=content)

[seand412]

Hi, I'm trying to create a Dash app which requires reading of SPC spectral files. Due to the quirks of Dash, I can't pass a file location, I have to read in the file contents. SpectroChemPy docs for the scp.read_spc() function (and other reads) state I can use the content kwarg to pass a bytes object instead. When I try (in a Jupyter notebook) though, I get an error message that states "ERROR | TypeError: 'WindowsPath' object is not subscriptable." in a red error box under the executed cell. There's no traceback provided.

The docs state there are examples on how to do what I'm trying in the tests/test_readers directory, but in my environment I can't find this directory. And the test_read_spc.py file that I found in an older version online just has a bunch of Assert tests to ensure files were read properly, not any examples on how to read spc file contents.

The file I'm trying to read is an SPC file, I read the bytes contents of it with with open(file, 'rb') as f: content = f.read(). I try reading the contents with f = scp.read_spc(content=content). Then I get the TypeError issue.

Any help would be much appreciated, let me know if you need more info and I'll see what I can do.

Thanks!
