1,官方文档
使用自定义函数及Python第三方库 (aliyun.com)
https://help.aliyun.com/document_detail/90716.html
2,查看本地python3版本和MaxCompute集群的版本
本地版本
MaxCompute集群内的python版本可以在mapper或者reducer方法里print(sys.version)看到
?这里可以看到本地是python 是3.6,MaxCompute是3.7
3,下载需要引入的包
MaxCompute集群内,只能通过官方文档的方法引入包,所以要先在外部下载好
pip3 download pandas -d /home/admin/workspace/zl/37/
因为本地python3 是3.6,有两个包是3.6的版本,而MaxCompute集群内的python是3.7,所以要把这俩包换成3.7的,可以去这里下载,把链接里的包名替换掉,就能看到不同的包了??????
https://mirrors.aliyun.com/pypi/simple/pandas/?spm=a2c4g.11186623.0.0.4bb97eebvJmf3S
引入pandas-ta 时,报错了
需要引入setuptools包
?引入之后,还有报错
这一步我是直接修改源码,重新打包解决的
4,创建资源
# 创建资源
# 注意,资源后缀与下载的包后缀必须一致,这些官方文档里有写
o.create_resource('numpy_zl.whl', 'archive', file_obj=open('../37/numpy-1.19.4-cp37-cp37m-manylinux1_x86_64.whl', 'rb'))
o.create_resource('pandas_zl.whl', 'archive', file_obj=open('../37/pandas-0.23.2-cp37-cp37m-manylinux1_x86_64.whl', 'rb'))
o.create_resource('python_dateutil_zl.whl', 'archive', file_obj=open('../38/python_dateutil-2.8.2-py2.py3-none-any.whl', 'rb'))
o.create_resource('pytz_zl.whl', 'archive', file_obj=open('../38/pytz-2022.1-py2.py3-none-any.whl', 'rb'))
o.create_resource('siz_zl.whl', 'archive', file_obj=open('../38/six-1.16.0-py2.py3-none-any.whl', 'rb'))

o.create_resource('pandas_ta.zip', 'archive', file_obj=open('../37/pandas_ta-0.3.14b.zip', 'rb'))
# o.create_resource('distribute.zip', 'archive', file_obj=open('../37/distribute-0.7.3.zip', 'rb'))
o.create_resource('setuptools_zl.whl', 'archive', file_obj=open('../37/setuptools-40.8.0-py2.py3-none-any.whl', 'rb'))?5,引用后,就可以在MaxCompute集群内使用pandas和pandas_ta了,附上源码
