好的,所以我有一个从CSV文件加载的numpy数组,该数组看起来像:
array([['0', '3', '22', ..., '7.25', '1', '0'],
['1', '1', '38', ..., '71.2833', '0', '0'],
['1', '3', '26', ..., '7.925', '1', '0'],
...,
['0', '3', '', ..., '23.45', '1', '0'],
['1', '1', '26', ..., '30', '0', '0'],
['0', '3', '32', ..., '7.75', '0', '0']],
dtype='|S8')
我想将数组元素转换为浮点型,但出现此错误
data2 = np.array(data).astype(np.float)
Traceback (most recent call last):
File "<input>", line 1, in <module>
ValueError: could not convert string to float:
有没有办法用numpy或pandas解决此问题?
