当我编译 TeX 文件时，出现错误

If you really absolutely need more capacity,
you can ask a wizard to enlarge me.
Here is how much of TeX's memory you used:
15863 strings out of 493482
285481 string characters out of 3137569
391082 words of memory out of 3000000
18829 multiletter control sequences out of 15000+200000
18450 words of font info for 71 fonts, out of 3000000 for 9000
957 hyphenation exceptions out of 8191
5000i,15n,7501p,2136b,954s stack positions out of 5000i,500n,10000p,200000b,50000s
Output written on transfer_report.dvi (21 pages, 84624 bytes).
但是，当我注释掉第二个图时，这个错误不会出现，并且我的 PDF 中会显示第一个图。此外，如果我在 transfer_report.tex 中注释掉以下几行，我可以编译 transfer_report.tex 并仍然在 PDF 中显示两个图
\node (lab1) [draw=none, below=0.3cm of dots1]{\LARGE $s_{(t - n + 1)}$};
\node (lab2) [draw=none, below=0.3cm of dots2]{\LARGE $s_{(t - n + 2)}$};
\node (lab3) [draw=none, below=0.4cm of dots3]{\LARGE $\ldots$};
\node (lab4) [draw=none, below=0.3cm of dots4]{\LARGE $s_{(t - 1)}$};
\node (lab5) [draw=none, below=0.3cm of dots5]{\LARGE $s_{(t)}$};
但是如果没有这 4 行代码，我的图就不完整。那么 (1) 为什么只有取消注释这 4 行代码时才会出现此错误？ (2) 我该如何修复此问题？
希望您说得清楚。如果您需要更多详细信息，请告诉我。谢谢！
