"Device" is not a known attribute of module "pycuda.driver". Pycuda 2025.1.1

Hello.

When I enter the lines, I get errors:
import pycuda.driver as drv
drv.init() #“init” is not a known attribute of module “pycuda.driver”
print(drv.Device.count()) # “Device” is not a known attribute of module “pycuda.driver”

Please advise on how to solve the problem.
Perhaps install Python 10 or roll back nvcc to version 12.01 (as suggested by AI).

I'm not a programmer, I just do a little programming for myself.
If it helps anyone, I installed:
cuda_11.8.0_522.06_windows
python-3.8.10-amd64
python -m pip install --upgrade pip
pip install numpy cython setuptools
pip install pycuda==2022.2.2

Everything seems to be working:
`import pycuda.autoinit
import numpy as np
import pycuda._driver as drv
from pycuda import gpuarray
print(drv.Device.count())

arr = gpuarray.to_gpu(np.array([1,2,3], dtype=np.float32))
print(arr.get() * 2)`
Output:
1
[2. 4. 6.]
