error while running example.py

Hi Amir, As your suggestion for adding argument "set_env_variable=False" in wave.WavePropagator, then I got this error

Hi, The error here is about picking the right platform and device to run the code.
It seems you need set_env_variable=True. You should define the right platform and device using inpa dictionary. You can use the following lines of code to see how many platforms you have and how many devices are available on each platform.

import pyopencl as cl

platforms = cl.get_platforms()
for platform in platforms:
    print(f"platform: {platform}")
    devices = platform.get_devices()
    gpu_devices = platform.get_devices(device_type=cl.device_type.GPU)
    cpu_devices = platform.get_devices(device_type=cl.device_type.CPU)
    print(f"Devices:\nAll: {devices}\nGPU: {gpu_devices}\nCPU {cpu_devices}\n {'='*16}")

Hi Amir,

I also met an error while creating the wave object with

W = wave.WavePropagator(inpa, src, rec_loc, model_shape, components=seisout, chpr=20)

the error message is

I have running the code

import pyopencl as cl

platforms = cl.get_platforms()
for platform in platforms:
    print(f"platform: {platform}")
    devices = platform.get_devices()
    gpu_devices = platform.get_devices(device_type=cl.device_type.GPU)
    cpu_devices = platform.get_devices(device_type=cl.device_type.CPU)
    print(f"Devices:\nAll: {devices}\nGPU: {gpu_devices}\nCPU {cpu_devices}\n {'='*16}")

and get the platform and Devices information

platform: <pyopencl.Platform 'NVIDIA CUDA' at 0x26a76cbd0a0>
Devices:
All: [<pyopencl.Device 'NVIDIA GeForce RTX 3070' on 'NVIDIA CUDA' at 0x26a76cbc290>]

@zj15001 Your system has only one device, but in the example, the device is set to 1. So, you should set the device in inpa to 0 before creating the wave propagator object. inpa["device"] = 0

Hi Amir, I have checked my device and obtained the following information：

platform: <pyopencl.Platform 'NVIDIA CUDA' at 0x37b8f30>
Devices:
All: [<pyopencl.Device 'NVIDIA GeForce RTX 3060 Ti' on 'NVIDIA CUDA' at 0x3818ed0>]
GPU: [<pyopencl.Device 'NVIDIA GeForce RTX 3060 Ti' on 'NVIDIA CUDA' at 0x3818ed0>]
CPU []

I have set ’ inpa["device"] = 0‘, but I have received a new error:

@petrolworker Another option is that you define inpa without the key device. Then create a wave propagator object as

wave.WavePropagator(inpa, src, rec_loc, model_shape, components=seisout, chpr=20, set_env_variable=False)

The important argument is set_env_variable=False that you should provide the wave propagator object with.
