RuntimeWarning: invalid value encountered in arcsin gamma = np.arcsin(K*T/dt)

This warning occurs when the input argument to the numpy arcsin function is not within the valid range of -1 to 1. The output of the arcsin function will be a NaN (Not a Number) value in this case.

To fix this warning, you can check whether the input argument is within the valid range before calling the arcsin function. For example:

if abs(K*T/dt) > 1:
gamma = np.nan
else:
gamma = np.arcsin(K*T/dt)

This code first checks whether the absolute value of K*T/dt is greater than 1. If it is, then gamma is set to NaN. Otherwise, the arcsin function is called with the input argument K*T/dt.

这些是运行时警告，可以忽略它们，因为它们不会影响程序的运行结果。但如果你想消除这些警告，可以尝试以下方法：

- 在代码中添加警告过滤器，例如：

  import warnings
  warnings.filterwarnings("ignore", category=RuntimeWarning)

- 尝试使用其他函数替代np.log10，例如np.log或math.log10
- 检查你的输入数据，可能存在零值或负数，导致出现无穷或非数值，可以尝试先对数据进行处理，例如加上一个很小的值以避免出现零值。
