has invalid type , must be a string or Tensor

has invalid type <class 'numpy.ndarray'>, must be a string or Tensor. (Can not convert a ndarray into a Tensor or Operation.)

 

原因：變量命名重復了

image_test, label_test = get_batch(x_val, y_val, w, h, batch_size, CAPACITY)

img_test, label_test = sess.run([image_test, label_test])

解決方法：把任意一個變量名改了就好了
