Could not find module 'C:\Users\thang\AppData\Roaming\Python\Python39\site-packages\thundergbm\thundergbm.dll' (or one of its dependencies). Try using the full path with constructor syntax.

Hi there, Many thanks for your good library. I have an issue when import TGBMClassifier: FileNotFoundError Traceback (most recent call last)

Please provide more information to help us reproduce the bug, such as your system information and CUDA version. Did you build the library by yourself or install it via pip?

[RNarayan73]

Hello, My system details are below: OS: Windows 11 Home Python: 3.9.13 cuda: 11.8 (this is cuda-python installed via conda; I don't have cuda installed directly in Windows)

I do not have C++ compilation tools and was looking for a ready to install package, so I picked up the latest win_amd64 that I thought would be appropriate and installed it. Installation was successful pip install thundergbm-0.3.12-py3-none-win_amd64.whl

But when trying to import TGBMClassifier: from thundergbm import TGBMClassifier I get the following error although the file exists in the location:

Traceback (most recent call last): File "", line 1, in File "C:\Anaconda3\envs\skl_py39\lib\site-packages\thundergbm__init__.py", line 10, in from .thundergbm import * File "C:\Anaconda3\envs\skl_py39\lib\site-packages\thundergbm\thundergbm.py", line 32, in thundergbm = CDLL(lib_path) File "C:\Anaconda3\envs\skl_py39\lib\ctypes__init.py", line 382, in init__ self._handle = _dlopen(self._name, mode) FileNotFoundError: Could not find module 'C:\Anaconda3\envs\skl_py39\lib\site-packages\thundergbm\thundergbm.dll' (or one of its dependencies). Try using the full path with constructor syntax.

Hope this helps.

Found this in the python documentation that may explain the issue: (https://docs.python.org/3/whatsnew/3.8.html#ctypes)

Hope this helps to fix the code.

Hello, @Kurt-Liuhf just wondering if you've had a chance to look into this yet?

I had met the same proble. It is because lack cusparse64_10.dll for 0.3.12 and cusparse64_100.dll for 0.3.4, download cusparse64_10.dll for 0.3.12 and put it it in C:\Windows\System32 or python_install_path\Lib\site-packages\thundergbm. it can work.
