Lorsque j'ai essayé d'afficher l'image dans le notebook Jupyter en l'exécutant, j'ai eu l'erreur suivante.
KeyError Traceback (most recent call last) /usr/local/lib/python3.6/dist-packages/PIL/Image.py in fromarray(obj, mode) 2415 typekey = (1, 1) + shape[2:], arr['typestr'] -> 2416 mode, rawmode = _fromarray_typemap[typekey] 2417 except KeyError:
KeyError: ((1, 1, 3), '<f4')
During handling of the above exception, another exception occurred:
TypeError Traceback (most recent call last) 1 frames /usr/local/lib/python3.6/dist-packages/PIL/Image.py in fromarray(obj, mode) 2417 except KeyError: 2418 # print(typekey) -> 2419 raise TypeError("Cannot handle this data type") 2420 else: 2421 rawmode = mode
TypeError: Cannot handle this data type
La modification du code comme suit a résolu le problème.
for i in range(100):
scale = 255.0 / np.max(X_test[i])
img = toimage(np.uint8(X_test[i]*scale))
label = results[i].argmax()
plt.subplot(10, 10, pos)
plt.imshow(img)
plt.axis('off')
plt.title(cifar10_labels[label])
pos += 1
plt.show()
