我不明白爲什麼numpy.genfromtxt
不能正確拆分使用delimiter=","
的下列字符串,而它適用於我的大部分其他字符串。numpy.genfromtxt:delimiter =','無法拆分字符串
chunk[12968]
Out[143]: '2901869281,3279442095,2012-12-15T23:00:00.003Z,Sacramento,CA,R#3817874,United States,38.583,-121.498,11, 8, 6, 5, 1, 0, 2, 3, 3, 5, 3, 3, 2, 2, 6, 6, 1, 2, 3, 0, 1, 1, 0, 0, 2, 2, 2, 2, 1, 0, 0, 2, 1, 0, 1, 1, 2, 0, 3, 1, 1, 1, 1, 0, 0, 4, 0, 0, 0, 1, 3, 1, 0, 2, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 2, 0, 9, 0, 0, 0, 2, 3, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0, 0,130\n'
我所期望的形狀(110)的陣列,但得到的是我使用izip_longest
從itertools
讀取由塊大* CSV這種方式下
genfromtxt([chunk[12968]],delimiter=",",dtype=np.int64)
Out[142]:
array([2901869281, 3279442095, -1, -1, -1,
-1], dtype=int64)
注:
with open('events.csv','r') as:
for chunk in izip_longest(*[f] *50000):
...
感謝您的幫助。
