老是报错ValueError: could not convert string to float:

老是报错，看了下文本也没有错，求大佬帮忙康康吧
path = "E:/Python code/pydata"  # 文件夹目录
files= os.listdir(path)  # 得到文件夹下的所有文件名称
txts = []
for file in files:  # 遍历文件夹
       position = path+'\\'+ file  # 构造绝对路径，"\\"，其中一个'\'为转义符
       print (position)
       with open(position, "r",encoding='utf-8') as f:    # 打开文件
                 # data = f.read()   # 读取文件
                 data = [[float(i) for i in line.strip().split(" ")] for line in f]   这一行报错
                 txts.append(data)

下面是报错内容：
Traceback (most recent call last):
  File "E:/Python code/octavefunction.py", line 56, in <module>
    data = [[float(i) for i in line.strip().split(" ")] for line in f]
  File "E:/Python code/octavefunction.py", line 56, in <listcomp>
    data = [[float(i) for i in line.strip().split(" ")] for line in f]
  File "E:/Python code/octavefunction.py", line 56, in <listcomp>
    data = [[float(i) for i in line.strip().split(" ")] for line in f]
