Question

将Python spaCy应用程序部署到AWS Lambda时，我在部署中遇到以下错误（请参阅下文）。为什么要使用zappa进行部署？ zip文件压缩为125MB，因此从aws-cli直接上传到空间失败，并且转移到S3也会失败，因为未压缩的文件超过250MB。

我的程序本身没有进行任何多线程处理，也没有多处理，它只使用spaCy 2.0。我在EC2 AWS Linux t2.medium上构建和部署。从spaCy AWS Lambda函数获得往返答案的具体步骤是什么？

我可以通过以下步骤解决该问题：

增加zappa_settings.json中的lambda函数的内存大小：

{ “ dev”：{
```
    "memory_size": 3008,
}
```
}
我必须使用更新版本的tqdm。默认情况下，版本为4.19，存在以下问题，如下所述：https://github.com/tqdm/tqdm/issues/466

所描述的问题已在较新的版本中修复。只需将tqdm添加到我的requirements.txt并对该软件包执行pip升级：

pip install -U tqdm

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，而tqdm 4.32.1是包含该修补程序的新版本。

使用zappa部署到AWS Lambda时，spaCy会抛出OSError
