Can't open ifc file like a bytes object

[Alexander Nabiev]

Hi everyone!
I need to open IFC file from minio S3 storage like a bytes object
Ifc file is stored in minio S3 storage. I can read it with minio module and i get file in "bytes type" (see below)

ifcfile = minioClient.get_object('nabievtest', 'OPU.ifc')
print(type(ifcfile.read()))

<class 'bytes'=""></class>

The file itself is correct, I check it with traditional way of open
But I can't read it this way from storage:

ifc_file = ifcopenshell.open(ifcfile.read())

TypeError: in method 'open', argument 1 of type 'std::string const &'

Can you explain me what i doing wrong?

open() expects the filename on disk as a python str not bytes.

If you have file content there is ifcopenshell.file.from_string() but it also expects a string so use ifcopenshell.file.from_string(ifcfile.read().decode('ascii'))

It works, thanks!
