Question

我正在尝试使用pyFFT计算FFT。但是以下代码会导致错误。

self.ctx = cl.create_some_context(interactive=False)            
self.queue = cl.CommandQueue(self.ctx)   
self.plan = Plan(fft_size, self.queue)   
gpu_data0 = cl_array.to_device(self.ctx, self.queue, ref_input)

ref_input的类型为：

< type 'numpy.ndarray' >

调试输出：

< pyopencl._cl.CommandQueue object at 0x7f0686c10628 >    
['__class__', '__delattr__', '__dict__', '__doc__', '__enter__', '__eq__', 
 '__exit__','__format__', '__getattribute__', '__hash__', '__init__', 
 '__instance_size__', '__module__', '__ne__', '__new__', '__reduce__', 
 '__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__', 
 '__subclasshook__', '__weakref__', '_get_cl_version', 'context', 'device', 
 'finish', 'flush', 'from_int_ptr', 'get_info', 'int_ptr', 'properties',    
 'reference_count']   

Traceback (most recent call last):
   File "../dsp.py", line 200, in gpu_fft
     gpu_data0 = cl_array.to_device(self.ctx, self.queue, ref_data)
   File "/usr/lib/python2.7/dist-packages/pyopencl/array.py", line 1446, in to_device
     if ary.dtype == object:
 AttributeError: 'CommandQueue' object has no attribute 'dtype'

事实上我找不到＆＃39; dtype＆＃39;。但为什么？

Answer 1

根据文档，函数pyopencl.array.to_device不会将上下文作为参数。请改用：

gpu_data0 = cl_array.to_device(self.queue, ref_input)

AttributeError：＆＃39; CommandQueue＆＃39;对象没有属性＆＃39; dtype＆＃39;
