How to deal with "multiprocessing.pool.RemoteTraceback"

[Destroy95]

Hello! When I configured the environment and then wanted to test it, when I entered the following command in the terminal

python run_tracker.py atom default --dataset_name otb --sequence Soccer --debug 1 --threads 8 --use_visdom False

such an error occurred

multiprocessing.pool.RemoteTraceback:

The above exception was the direct cause of the following exception:

Have you tried running with a --thread 0 ? Does this work?

I tried, but it also has similar problems

Looks like something could be wrong with your init_info.get('init_box'). Can you try printing it? or the box array? Alternatively you can try to run dimp or another dataset to debug this further... Btw. did you change the default.py parameter file? In particular did you setparams.visualizaton = True here? I don't understand why the function self.visualize() is called in your case... Using visdom is preferable and much nicer to use than matplotlib...

OK, thank you so much! I'll try printing it out to see the result.

看起来您的.你能尝试打印它吗？还是阵列？或者，您可以尝试运行 dimp 或其他数据集来进一步调试...顺便说一句，您是否更改了参数文件？特别是你设置在这里吗？我不明白为什么在您的情况下调用该函数...使用 visdom 比 matplotlib 更可取，而且使用起来更好......init_info.get('init_box')``box``default.py`` params.visualizaton = True``self.visualize()

I have the same question,how can I do to solve it

Does anyone solve this issue?
