使用MemoryError的CVS2SVN

Question

我正在尝试使用csv2svn将CSV存储库迁移到SVN。在第一次传递(CollectRevsPass)期间处理了一些错误之后，我进入了第四步，出现了这个错误：

MemoryError

当出现此错误时，我检查并有足够的空闲内存。就在错误出现之前，进程'python‘大大增加了内存的使用。

有人知道我能做什么吗？

• CVS2SVN 2.4
• Python 2.7

Answer 1

此错误还可能表示该进程已耗尽虚拟地址空间。如果您在32位模式下运行cvs2svn，那么进程只有一些类似于2 GiB或4 GiB的地址可以使用，不管计算机是否有空闲内存。如果是这样的话，尝试以64位模式运行程序.

如果您已经以64位模式运行，请尝试增加RAM或交换空间，或在增强计算机上运行该程序。
