This tutorial explains how we can convert the NumPy array to aPILimage using theImage.fromarray()from thePILpackage. The Python Imaging Library (PIL) is a library in Python with various image processing function
image = PIL.Image.open(file_name) lst.append(np.array(image)) arr = numpy.array(lst) 即,在list中的元素都已转化为numpy.array,而非直接的Image对象。

错误信息 'numpy.ndarray' object has no attribute 'convert' 明确指出,你尝试在一个 numpy.ndarray 对象上调用了一个不存在的 convert 方法。这意味着 numpy 的数组对象没有提供名为 convert 的方法。 2. 确认问题原因 这个问题通常是由于代码错误引起的。可能的原因包括: ...
