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。
Matplotlib is a widely used plotting library in Python that allows users to create various types of visualizations. One common task you might across when working with Matplotlib is to convert a plotted figure into a NumPy array. This conversion can be useful in scenarios where you want to manip...
In Python 3 it does not work anymore: importnumpyasnp f =lambdax: x**2seq =map(f,range(5)) seq = np.array(seq)print(seq)# prints: How do I get the old behaviour (converting the map results to numpy array)? Answer Use np.fromiter: importnumpyasnp f =lambdax: x**2seq =ma...
