I want to install **pycuda** but get failed. My **jetpack** is 5.1.3. The **cuda** version is 11.4. I already added path:

```auto
export PATH=/usr/local/cuda-11.4/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda-11.4/lib64/{LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

```

I tried to install pycuda via the source codes by:

```auto
python3 configure.py --cuda-root=/usr/local/cuda-11.4
sudo python3 setup.py install

```

The results show the following which implies **pycuda** is installed:

```auto

```

But if I cd to test folder and run the **test\_driver.py** , the shell tells

```auto
Traceback (most recent call last):
  File "test_driver.py", line 8, in <module>
    from pycuda.tools import mark_cuda_test, dtype_to_ctype
ModuleNotFoundError: No module named 'pycuda'

```

and I can’t find **pycuda** in `pip list`. Can you help me fix this?

Hi,

Sorry for the late update.  
Could you try to add the folder to `PYTHONPATH` and try it again?

For example:

```auto
$ echo 'export PYTHONPATH=/usr/lib/python3.8/site-packages/:$PYTHONPATH' >> ~/.bashrc
$ source ~/.bashrc

```

Thanks.
