我正在使用一个需要 NumPy 的包。到目前为止，它工作正常。但是今天，由于扩展了我的代码，我需要最新版本的 NumPy。旧版本是 17.something，我安装了最新版本。之后我面临下面提到的问题Github上问题的详细链接
File "C:\Users\AppData\Local\Programs\Python\Python38-32\lib\site-packages\numpy\core\function_base.py", line 119, in linspace
raise TypeError(
TypeError: object of type <class 'numpy.float64'> cannot be safely interpreted as an integer.
将您的numpy版本降级到： 1.16
pip install numpy==1.16
为我工作。
在 1.17 的 numpy 中
In [216]: np.linspace(0,1,10.)
Out[216]:
array([0. , 0.11111111, 0.22222222, 0.33333333, 0.44444444,
0.55555556, 0.66666667, 0.77777778, 0.88888889, 1. ])
更新到 1.18
In [2]: np.linspace(0,10,10.)
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)

116 try:
--> 117 num = operator.index(num)
118 except TypeError:
TypeError: 'float' object cannot be interpreted as an integer
During handling of the above exception, another exception occurred:

123 if num < 0:

该num = operator.index(num)测试曾经在deprecation警告功能中num = _index_deprecate(num)，现在它引发了错误。

我偶然发现了这个错误，不需要降级。
np.linspace(0,1,int(10.))
该num值需要作为整数传递。
