I have a jetson xavier. I installed the operating system I thought jetpack came with cuda installed and all the gpu drivers but when i try to use pycuda it is telling me I dont have the drivers.

```
import pycuda.driver as cuda

```

File “/home/throwaway/Downloads/pycuda/pycuda/driver.py”, line 62, in   
from pycuda.\_driver import \* # noqa  
ImportError: No module named \_driver

Any info on setting up python gpu environment and where to download all the gpu drivers for jetson xavier?

thanks.

Hi,

How do you install pyCUDA?

I can import pyCUDA without issue after this installation command:

```auto
pip3 install numpy pycuda --user

```

```auto
$ python3
>> import pycuda.driver as cuda

```

Thanks.

python3

I get  
from pycuda.\_driver import \* # noqa  
ModuleNotFoundError: No module named 'pycuda.\_driver

ok I think it was because I was trying to run files importing pycuda from within the directory I downloaded pycuda

Hi,

So the issue is fixed after changing the directory, right?  
Thanks.

Yep I guess pycuda couldn’t find the files while trying to execute from the directory that it was downloaded in
