python中如何显示带子图像的图像

Question

fig, ax = newfig(1.0, 0.9)
ax.axis('off')    
gs0 = gridspec.GridSpec(1, 2)
gs0.update(top=0.85, bottom=0.25, left=0.1, right=0.95, wspace=0.3)

ax = plt.subplot(gs0[:, 0:1])
ax.plot(t_star,X_star[:,0],'r',label='$x$')
ax.plot(t_star,X_star[:,1],'b',label='$y$')
ax.plot(t_star,learned_X_star[:,0],'k--',label='learned model')
ax.plot(t_star,learned_X_star[:,1],'k--')    
ax.set_xlabel('$t$')
ax.set_ylabel('$x, y$')
ax.legend(loc='upper center', bbox_to_anchor=(0.9, -0.25), ncol=3, frameon=False)
ax.set_title('Trajectories', fontsize = 10)

ax = plt.subplot(gs0[:, 1:2])
ax.plot(X_star[:,0],X_star[:,1], 'm', label='$(x,y)$')
ax.plot(learned_X_star[:,0],learned_X_star[:,1],'k--')
ax.set_xlabel('$x$')
ax.set_ylabel('$y$')
ax.legend(loc='upper center', bbox_to_anchor=(0.4, -0.25), ncol=1, frameon=False)
ax.set_title('Phase Portrait', fontsize = 10)

    这段代码如果要显示图像应该怎么写呢？写plt.show(),  plt.ion(),   Image.show()都不行，是不是要重新导入 matplotlib包呢？运行总显示这个包有错误
