pandas将numpy数组写入到csv

直接代码

data_arr = []
data = iter_files(dir,speakers)
for k,v in data.items():
    data_arr.append([k,v])
# print(data_arr)
import numpy as np

np_data = np.array(data_arr)

##写入文件
pd_data = pd.DataFrame(np_data,columns=['filename','gender'])
print(pd_data)
pd_data.to_csv('pd_data.csv')
