我试图使用python中提供的'dump'命令将字典转换为pickle格式.字典的文件大小约为150 MB,但只有115 MB的文件被转储时才会出现异常.例外是:

Traceback (most recent call last): 
  File "C:\Python27\generate_traffic_pattern.py", line 32, in <module> 
    b.dump_data(way_id_data,'way_id_data.pickle') 
  File "C:\Python27\class_dump_load_data.py", line 8, in dump_data 
    pickle.dump(data,saved_file) 
  File "C:\Python27\lib\pickle.py", line 1370, in dump 
    Pickler(file, protocol).dump(obj) 
  File "C:\Python27\lib\pickle.py", line 224, in dump 
    self.save(obj)

    f(self, obj) # Call unbound method with explicit self

我正在使用迭代循环来使用Matplotlib绘制soame数据.当代码保存了大约768个图时,它会抛出以下异常.

RuntimeError: Could not allocate memory for image

我的电脑有大约3.5 GB的RAM.是否有任何方法可以并行释放内存,以免内存耗尽？

对于以下代码:

local function getParentPath(_path)

    pattern = "(.+)([/\\][/\\])(.+)"
    i,j,k = string.match(path,pattern)
    return i,j,k

end

print(getParentPath(path))

对于path ="C://data//file.text",我得到:

C://data // file.text

但是对于path ="C:\ data\file.text",我得到:

nil nil nil

我正在寻找一种适合两者的模式.有什么建议？

我有一个包含几个功能块的文本文件,其中一些是重复的.我想创建一个只包含唯一功能块的新文件.例如input.txt(我已经更新了示例):

Func (a1,b1) abc1
{
xyz1;
    {
        xy1;
    }

xy1;
}

Func (a2,b2) abc2
{
xyz2;
    {
        xy2;
        rst2;
    }

xy2;
}

Func (a1,b1) abc1
{
xyz1;
    {
        xy1;
    }

xy1;
}

Func (a3,b3) abc3
{
xyz3;
    {
        xy3;
        rst3;
        def3;
    }

xy3;
}
    Func (a1,b1) abc1
{
xyz1;
    {
        xy1;
    }

xy1;
}

并希望将output.txt作为:

Func (a1,b1) abc1
{
xyz1;
    {
        xy1;
    }

xy1;
}

Func (a2,b2) abc2
{
xyz2;
    {
        xy2;
        rst2;
    }

xy2;
}

Func (a3,b3) abc3
{ …
