python - 使用zappa部署到AWS Lambda时，spaCy引发OSError

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（请参见下文）。为什么使用Zappa部署？zip文件是125mb压缩的，因此aws cli的直接上载在空间上失败，而传输到s3的操作也失败，因为未压缩的文件超过250mb。
我的程序本身不做任何多线程或多处理，它只使用Spacy2.0。我在ec2awslinuxt2.medium上构建和部署。从spacy aws lambda函数获得往返答案的确切步骤是什么？
故障跟踪如下：

最佳答案

我可以通过以下步骤解决问题：
在zappa_settings.json中增加lambda函数的内存大小：
{
“开发”：{

    "memory_size": 3008,
}

}
我不得不使用新版本的tqdm。默认情况下，版本为4.19，出现了如下所述的问题：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myrequirements.txt并对包执行pip升级：

pip install -U tqdm

当我执行zappa deploy dev时，现在得到以下消息：
（tqdm 4.32.1（/var/task/ve/lib/python3.6/site包），Requirement.parse（'tqdm==4.19.1'），{'zappa'}）
TQM4.19.1是zappa的默认版本，TQM4.32.1是包含修复程序的新版本。
