Question

我正在生成图形并将其保存到指定的文件夹，但是在该特定目标中没有任何图形被保存。该图形仅生成一次，此后出现错误。这是我的代码

 import numpy as np
import matplotlib.pyplot as plt

final_obj=np.array([[  8.31907313 ,  0.17300669],
 [  8.50432396 ,  0.19566612],
 [  8.50432396 ,  0.19566612],
 [  8.50432396  , 0.19566612],
 [  8.50432396   ,0.19566612],
 [  8.50432396  , 0.19566612],
 [  8.50432396  , 0.19566612],
 [  8.50432396  , 0.19566612],
 [  8.50432396  , 0.19566612],
 [  8.50432396  , 0.19566612],
 [  8.50432396   ,0.19566612],
 [  8.50432396   ,0.19566612],
 [  8.50432396   ,0.19566612]])

print(final_obj)
x1=[]
y1=[]
for z in range(0,5):
     for i in range(0,len(final_obj)):
          X=final_obj[i][0]
          x1.append(X)
          Y=final_obj[i][1]
          y1.append(Y)


     plt.plot(x1, y1, label = "line 1",marker='o',linestyle = 'None')
     plt.xlabel("X-axis")
     plt.ylabel("Y-axis")
     plt.legend()
     plt.show()
     save_results_to = "C:\\Users\hp\PycharmProjects\SRMMEA\venv\IRIS_GRAPH"
     plt.savefig(save_results_to+'GRAPH_{}.png'.format(z), format="PNG")

它显示了以上代码的错误

Answer 1

save_results_to = "C:\\Users\hp\PycharmProjects\SRMMEA\venv\IRIS_GRAPH"

用上述代码替换上面的代码以获得所需的结果

save_results_to = "C:\\Users\\hp\\PycharmProjects\\SRMMEA\\venv\\IRIS_GRAPH\\"

不将图形保存到指定文件夹
