spaCy在使用zapp部署到AWS Lambda时抛出OSError

Question

在将Python spaCy应用程序部署到AWS Lambda时，我在部署中得到以下错误（见下文）。为什么使用zappa部署？压缩的zip文件是125MB的，因此从AWSCLI直接上载空间失败，而传输到S3的操作也失败，因为未压缩的文件超过250MB。在

我的程序本身不执行任何多线程或多处理，它只使用spacy2.0。我构建并部署在ec2awslinuxt2.medium上。从spaCy AWS Lambda函数获得往返答案的确切步骤是什么？在

Answer 1

我可以通过以下步骤解决问题：

1. 增加zappa_settings.json中lambda函数的内存大小：

   在{ “开发”：{

       "memory_size": 3008,
   }
   

   }

2. 我不得不使用更新版本的tqdm。默认情况下，版本4.19存在如下问题：https://github.com/tqdm/tqdm/issues/466

所述问题已在较新版本中修复。只需将tqdm添加到我的requirements.txt并执行包的pip升级：

当我执行zappa deploy dev时，我得到以下消息：

(tqdm 4.32.1 (/var/task/ve/lib/python3.6/site-packages), Requirement.parse('tqdm==4.19.1'), {'zappa'})

tqdm 4.19.1是zappa的默认版本，tqdm 4.32.1是包含修复程序的新版本。在
