Required prerequisites

• Consult the security policy. If reporting a security vulnerability, do not report the bug using this form. Use the process described in the policy to report the issue.
• Make sure you've read the documentation. Your issue may be addressed there.

• If possible, make a PR with a failing test to give us a starting point to work on!

Describe the bug

I tried to run the demo on https://nvidia.github.io/cuda-quantum/latest/applications/python/vqe_advanced.html directly in the interpreter. It fails with the following:

>>> import cudaq
>>> @cudaq.kernel
... def kernel(qubit_num: int, electron_num: int, thetas: list[float]):
...     qubits = cudaq.qvector(qubit_num)
...
OSError: could not get source code

Steps to reproduce the bug

Type this into the interpreter and press return:

>>> import cudaq
>>> @cudaq.kernel
... def kernel(qubit_num: int, electron_num: int, thetas: list[float]):
...     qubits = cudaq.qvector(qubit_num)
...
OSError: could not get source code

Expected behavior

What the documentation describes on the aforementioned page.

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression

Environment

• CUDA-Q version: latest. I ran pip install --upgrade cudaq today.
• Python version: 3.10.12
• C++ compiler: GCC 11.4
• Operating system: Ubuntu 22.04.5 LTS
