Array API

I believe there's an issue with passing in any value to _asarray. The function refuses to create this image's values despite tedious restructuring. I can provide more code and details if you like, but here is the general code implementation below.
```
filename = "godfather.jpg"
img = mpimg.imread(filename)
img = rgb2gray(img)
plt.imshow(img, cmap='gray')
def flatten_comprehension(matrix):
return [item for row in matrix for item in row]
imgL = flatten_comprehension(img)
image = np.reshape(np.asarray(imgL, dtype=np.float32), (600, 900), copy=True)
gradient_magnitude, gradient_direction = sobel_filters(image)
```

img when implemented here is just an nparray from .imread, have to do a lot of weird tricks to get around the first error (worked w @syurkevi on this)
here's the error stack trace

```

Comece reproduzindo o exemplo de processamento de imagem fornecido e inspecione a implementação de _asarray em torno da linha 145 relatada, especialmente o acesso a Array._array. Confirme por que o caminho ndarray gera AttributeError e defina done como processar a entrada mostrada sem essa exceção; nenhuma test do repositório ou arquivo-fonte é nomeado na issue.
