我有这个脚本可以并行绘制许多图形。当我在ipython中运行它以对其进行测试时，它运行良好，但是当我提交要并行运行的作业脚本时，尝试注释某些文本时会失败。失败的部分如下：
time_string = "$t$="+str(int(time_val))+"yr"
time_string_raw = r'{}'.format(time_string)
time_text = ax.text((xlim[0]+0.01*(xlim[1]-xlim[0])), (ylim[1]-0.03*(ylim[1]-ylim[0])), time_string_raw, va="center", ha="left", color='w', fontsize=args.text_font)
plt.savefig("Test_802.jpg", format='jpg', bbox_inches='tight')
错误消息是：
