python numpy数据保存csv

np.savetxt('all_data_6.csv', all_data_6, delimiter = ',')
np.savetxt('all_data_8.csv', all_data_6, delimiter = ',')

读入csv 为np.array

counts_8bands = genfromtxt("counts_8bands.csv", delimiter=',', skip_header=True)
all_data_8bandslist = list(np.int_(all_data_8bands))
counts_8bandslist = list(np.int_(counts_8bands))


import csv
all_data_8bands = csv.reader(open("all_data_8bands.csv"))
counts_8bands = csv.reader(open("counts_8bands.csv"))
