Похоже, что это сработает, если вы будете осторожны в использовании Python2.7 и начнете облачный проект с последним приложением Python2.7 SDK. Я запустил докер-контейнер для python: 2 ("docker run -it python:2 bash"), установил gcloud sdk, установил pip sympy, запустил dev_appserver и получил ответ от localhost, который выглядит как успех. Шаги были:
1 apt update
2 apt install git
3 pip install sympy
4 pip install wget
5 wget https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-sdk-271.0.0-linux-x86_64.tar.gz
6 tar xvf google-cloud-sdk-271.0.0-linux-x86_64.tar.gz
7 ./google-cloud-sdk/install.sh
8 ./google-cloud-sdk/bin/gcloud init
9 git clone git://github.com/sympy/sympy_gamma.git
10 cd sympy_gamma
11 git submodule init
12 git submodule update
13 python deploy.py --generate-only --generate-test 1000
14 ../google-cloud-sdk/bin/dev_appserver.py . &
15 wget http://localhost:8080
16 cat index.html
Некоторые выходные данные, чтобы показать вам ответ, который я получил:
