Question

我使用pytorch多处理模块生成体验并将其存储在manager.list（）对象中。该过程停止后，我尝试索引存储在全局共享列表对象中的体验，并得到以下错误消息。我可以打印全局对象，但不能为其编制索引：

Unserializable message: Traceback (most recent call last):

    (device, handle, storage_size_bytes, storage_offset_bytes) = storage._share_cuda_()
RuntimeError: invalid device pointer: 0x204aa0000 at /opt/conda/conda-bld/pytorch_1544173631724/work/aten/src/THC/THCCachingAllocator.cpp:301

有解决方案吗？谢谢。

使用pytorch多重处理，manager.list收到无效的设备指针错误
