No module named "_libvips"

[ReallyRad]

Hello,

After installing kubi with pip I'm unable to run any commands because of the following error :

`ModuleNotFoundError: No module named '_libvips'

During handling of the above exception, another exception occurred:

Traceback (most recent call last): File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\runpy.py", line 196, in _run_module_as_main return _run_code(code, main_globals, None, File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\runpy.py", line 86, in _run_code exec(code, run_globals) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\Scripts\kubi.exe__main.py", line 7, in File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\kubi\kubi.py", line 347, in run main(sys.argv[1:]) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\kubi\kubi.py", line 343, in main kubi(args) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\kubi\kubi.py", line 38, in kubi import pyvips File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\pyvips\init__.py", line 70, in gobject_lib = ffi.dlopen(_gobject_libname) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\cffi\api.py", line 150, in dlopen lib, function_cache = _make_ffi_library(self, name, flags) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\cffi\api.py", line 832, in _make_ffi_library backendlib = _load_backend_lib(backend, libname, flags) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\cffi\api.py", line 827, in _load_backend_lib raise OSError(msg) OSError: cannot load library 'libgobject-2.0-0.dll': error 0x7e. Additionally, ctypes.util.find_library() did not manage to locate a library called 'libgobject-2.0-0.dll'`

I'm using python 3.10

Any suggestions?

thanks

You have to also install the required libraries mentioned here: https://github.com/indus/kubi?tab=readme-ov-file#requirementsAm 09.02.2024 12:44 schrieb ReallyRad @.***>: Hello, After installing kubi with pip I'm unable to run any commands because of the following error : ModuleNotFoundError: No module named '_libvips' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\runpy.py", line 196, in _run_module_as_main return run_code(code, main_globals, None, File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\runpy.py", line 86, in run_code exec(code, run_globals) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\Scripts\kubi.exe_main.py", line 7, in File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\kubi\kubi.py", line 347, in run main(sys.argv[1:]) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\kubi\kubi.py", line 343, in main kubi(args) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\kubi\kubi.py", line 38, in kubi import pyvips File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\pyvips_init.py", line 70, in gobject_lib = ffi.dlopen(_gobject_libname) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\cffi\api.py", line 150, in dlopen lib, function_cache = _make_ffi_library(self, name, flags) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\cffi\api.py", line 832, in _make_ffi_library backendlib = _load_backend_lib(backend, libname, flags) File "C:\Users\Arthur\AppData\Local\Programs\Python\Python310\lib\site-packages\cffi\api.py", line 827, in _load_backend_lib raise OSError(msg) OSError: cannot load library 'libgobject-2.0-0.dll': error 0x7e.

Hello, numpy 1.26.4 and pyvips 2.2.2 are indeed installed. Could you share the recommended versions of python and of those two packages? thanks

I don't have the versions at hand (I can look for them later). Another problem may be a missing libvips binary in the path (you are working in Windows, right?). If that is the case you can set a flag in kubi that points to the libvips bin folder or add it to the path variable.Am 09.02.2024 15:12 schrieb ReallyRad @.***>: Hello, numpy 1.26.4 and pyvips 2.2.2 are indeed installed.

@ReallyRad Did you had success already?

I would first try to follow the pyvips installation guide: https://github.com/libvips/pyvips?tab=readme-ov-file#windows-install First download this: https://github.com/libvips/build-win64-mxe/releases/download/v8.14.4/vips-dev-w64-all-8.14.4.zip unzip it to your filesystem and then use kubi like so: kubi --vips path/to/the/vips/bin ... (this will add the folder to PATH as described in the pyvips installation guide: https://github.com/indus/kubi/blob/main/src/kubi/kubi.py#L34-L36).

But because you asked - I'm running kubi with:

• python 3.10.2
• pyvips 2.2.1
• numpy 1.24.1

But that is not a recommendation - just my currently installed versions ;-) And I don't think the problem is caused by those minor misalignments.
