Cannot generate plotting plan

[MagicLoki]

loki@loki-virtual-machine:~/Desktop$ sudo splatplan -i inkling.png -o test [sudo] loki's password： Blocks to be visited: 0%| | 0/24 [00:00<?, ?it/s]

The execution progress of the program stopped at 0%. After I waited for a few minutes, the terminal interface closed automatically. I tried several times and all failed

Using Ubuntu 22.04.1 LTS

Hello, can you provide your inkling file so we can look into it? thanks

[TattlingElk]

I have the exact same problem on my end, one of my files can get to 2/24 before crashing as well. Is there a specific way to prepare our images to make it work?

[Victrid]

@MagicLoki @TattlingElk Maybe it's the memory problem. the plotting plan is getting quite large if you have lots of not-connected item on them.

I'll add a "continue" option to the plotter, and change the planning strategy, which allows to plot in multiple runs.

[Victrid]

You can open the system monitor (系统监视器？) or htop to view if out-of-memory causes the problem.

I now assign Ubuntu 8G of memory, but it still doesn't help, it looks like the CPU is full

[Victrid]

@MagicLoki It fills up my 32G memory machine

It seems that the DP algorithm solving TSP problem is taking too much memory.

I'll fix the memory issue as soon as I can.

@Victrid I do appreciate your hard work towards the optimization of the plotting algorithm, while I think a much simpler solution would be realeasing a version of splaplost without any optimization algorithm. (Just scanning lines when plotting) After all, the plotting time without optimization is fairly acceptable. (Just a little bit more hours I think🤔)(And it's much easier to correct any plotting error when scanning plotting)(Also it could save us from installing countless python data science packages and their dependencies😂)

I'll dive into that, but removing data science packages completely would be much harder to handle matrices.

At least we need to have numpy :joy:

[Logic530]

@Victrid numpy is totally fine😂

[TattlingElk]

I can confirm that using an image that is much more simple in graphics does indeed go through successfully.

@Victrid 还有个想法就是放弃掉蓝牙控制部分的代码，仅保留计算路径的功能，将计算的路径结果输出为 NXBT 的宏脚本，直接配合使用 NXBT 的从文件运行宏指令的方法画图。原因包括 NXBT 的安装体验还是修的比较好的，使用命令行敲一下就能自动安装成功，相对的今天下午我尝试sudo pip install splatplost就一直失败 (在全新的 ubuntu desktop 22.04 虚拟机环境下 python-dbus装不上) (死去的配环境记忆开始攻击我)，以及少维护一部分代码可以省很多精力 (更多时间用于优化算法)，目前的splatplan命令的功能只需一些微小的修改就可以实现上述效果。NXBT 运行宏的便捷度和稳定性我体验感觉都没什么问题 (用旧版的 insgen.py 生成的 .order 文件手动修改格式作为 NXBT 宏运行) (经我测试将按键按下和松开之间的间隔设置为 0.08s 可以稳定运行不会吞键) 以上，不好意思给作者提了这么多要求，但过两天喷三就要出了啊，还是希望能让更多人第一时间用上，非常感谢。

[Victrid]

吞键应该主要是蓝牙链接不稳定的问题。这个跟蓝牙无线网卡的质量关系比较大，而且时间设长了又会导致识别为连键。

python-dbus应该是nxbt的依赖，现在蓝牙部分都是NXBT在干。

把nxbt加在代码里而不是单独列出，主要还是希望之后能够把以USB手柄连接的方法合并进来，稳定性比蓝牙的实现高很多。

现在正在搞断点恢复和修复重画错误图形的功能，喷3出了之后应该会更方便，因为喷3的橡皮是绑在B键上的。

By now the figure can be generate correctly. Please update splatplost to version 0.1.4+ with pip.

pip install -U splatplost

This will also introduce the stable mode, add --stable to the command line to enable it.
