python使用subplots绘图

请问如何让下图的[1,2]位置处不显示坐标线，谢谢

fig, ax = plt.subplots(2,3)

for i in range(2):
    for j in range(3):

        if i==1 and j==2:
            continue

        im = ax[i,j].imshow(harvest[3*i+j])
    
        ax[i,j].set_xticks(np.arange(len(farmers)))
        ax[i,j].set_yticks(np.arange(len(vegetables)))
        ax[i,j].set_xticklabels(farmers)
        ax[i,j].set_yticklabels(vegetables)

设置 ax[i,j].axis("off")
