我正在编写一个累积消耗内存的脚本，我不知道如何解决这个问题。任何帮助或建议都表示赞赏。
Python垃圾收集器以某种方式失败，发生了什么？
代码示例如下，一些注意事项如下
我怀疑罪魁祸首是psspy，但我无法访问其代码，是否有某种解决方法？
ierr都是整数
variable1等是包含单个数字列表（整数，实数或复合数）的列表。
import psspy
psspy.psseinit(1200)
cases = []
... #Construction of a list of strings containing filenames like 'case010.sav'
faults = []
... #Construction of another list that doesn't contribute to the problem.
for filename in cases:
psspy.case(filename) #It opens a 'case' that alters the output of the following functions
ierr, variable1 = psspy.function1(parameters)
ierr, variable2 = psspy.function2(parameters)
...
ierr, variablen = psspy.functionn(parameters)
...
for fault in faults:
psspy.close_powerflow() #Documentation says it
#'Removes the current powerflow working case from PSS®E’s working memory.'
psspy.case(filename)
...
ierr, variable1 = psspy.function1(parameters)
ierr, variable2 = psspy.function2(parametersl)
...
ierr, variablen = psspy.functionn(parameters)
...
