我已经正确部署了python3 App building-an-app：
但是现在我尝试部署使用神经网络的应用程序，并且该应用程序在本地可以通过virtualenv并使用requeriments.txt文件正常运行：
Flask==1.1.1
numpy==1.17.4
scipy==1.3.2
gensim==3.8.1
tensorflow==2.0.0
但是当我使用“ gcloud app deploy”时，在5分钟后显示此消息“正在更新服务[默认] ...”，则出现此错误：

任何人都知道可能是什么问题吗？
检查构建日志中的错误，发现其中一行显示：
Step #1 - "builder": exited with error [Errno 12] Cannot allocate memory
所以我将app.yaml更改为：
runtime: python37
handlers:
# This configures Google App Engine to serve the files in the app's static
# directory.
- url: /static
static_dir: static
# This handler routes all requests not caught above to your main app. It is
# required when static routes are defined, but can be omitted (along with
# the entire handlers section) when there are no static files defined.
- url: /.*
script: auto
resources:
cpu: 2
memory_gb: 8
disk_size_gb: 10
但是我仍然遇到相同的错误：（

谢谢！
您遇到的错误似乎表明您正在使用的GAE实例正在运行内存不足。
作为一种选择，您可能想尝试将实例的class更改为具有更高内存限制的实例。
