How to convert a list of floats to integer in the Python programming language - List comprehension - map() function & numpy array
import numpy as np # 创建一个包含字符串的NumPy数组 arr = np.array(['1', '2', '3']) # 使用map()函数将字符串列表转换为整数列表 arr_int = list(map(int, arr)) 在上面的例子中,我们使用map()函数将int()函数应用于数组的每个元素,将字符串列表转换为整数列表。这种方法适用于任何可应用于单...
on numpy 1.x >>>importnumpyasnp>>>x=np.ones(4)>>>tuple(x) (1.0,1.0,1.0,1.0) This will cause colors to return an unexpected data type, so change it to tolist() to ensure that the builtin Python type is returned. This PR was raised because the downstream repo had a negative im...

Look in the output; it converted the given list of strings into a tensor, which istf.Tensor([b’Chicago’ b’Houston’ b’Dallas’], shape=(3,), dtype=string). Similarly, you can convert anything in the list to a tensor using thetf.convert_to_list()function. ...
