編輯我已經生成一個CSV文件，它看起來像這樣一個CSV文件

我想將它重新構造這樣的，它應該只有一個行，根本沒有列。我試過numpy.genfromtxt

new=np.genfromtxt('repaired.csv', dtype='float', delimiter=',', skip_header=0, skip_footer=0, converters=None, missing_values=None, filling_values=None, usecols=None, names=None, excludelist=None, deletechars='"', replace_space='_', autostrip=False, case_sensitive=True, defaultfmt='f%i', unpack=None, usemask=False, loose=True, invalid_raise=True, max_rows=None) 

但它沒有工作。我在歌廳錯誤爲：

ValueError: Some errors were detected ! 
    Line #1591 (got 28 columns instead of 32) 
    Line #1593 (got 4 columns instead of 32) 

Answer 1

我都這樣對csv文件轉換完成到numpy array

import csv 
import numpy as np 
data_in_csv_file = [] 
# reading the csv file 
with open('hello2.csv', 'r') as f: 
    reader = csv.reader(f) 
    for row in reader: 
     data_in_csv_file.append(row) 
# removing the empty row of the csv file 
# and convert into a list 
list_values = sum(data_in_csv_file,[]) 
# converting numpy array 
values = np.array(list_values) 
print(values) 

Answer 2

如果你有可能使用​​你可以試試這個：

import pandas 

new = pandas.read_csv('repaired.csv', sep=',', engine='python', header=None) 

在CSV必須之中，雖然最長行的第一行，否則將不工作。

，如果你需要你的數據作爲純numpy數組，你可以把它轉換：

nm = new.as_matrix()
