numpy output data not displayed in scientific notation

To prevent numpy from displaying scientific notation when outputting data, you can use numpy's set_printoptions() function and set its parameter suppress to True. For example:

import numpy asnp

np.set_printoptions(suppress=True)

a = np.array([1.23456789])
print(a)  # 输出 [1.23456789] 而不是 [1.23457]
