python - 将 R 代码转换为 Python 的问题

Question

from pyensae.languages import r2python

print(r2python(rscript, pep8=True))

我在将 filename.R 转换为 pythonfilename.py 时遇到问题，因为这些库对转换没有用，因为即使我安装了它也会生成错误“找不到模块”该模块使用:

pip install pyensae

Answer 1

以下步骤适用于 Python 版本 Python 3.7.6。

1. 升级你的pip

python -m pip install --upgrade pip

1. 安装pyensae模块

pip install pyensae

1. 通过执行下面的 import 检查你的 python 控制台

from pyensae.languages import r2python

如果你面对

ModuleNotFoundError: No module named 'antlr4'

或面向

ModuleNotFoundError: No module named 'builtin'

然后执行下面的命令

pip install antlr4-python3-runtime

经过上述步骤，我可以将R脚本转换成python语言

rscript = """
nb=function(y=1930){
debut=1816
MatDFemale=matrix(D$Female,nrow=111)
colnames(MatDFemale)=(debut+0):198
cly=(y-debut+1):111
deces=diag(MatDFemale[:,cly[cly%in%1:199]])
return(c(B$Female[B$Year==y],deces))}
"""
from pyensae.languages import r2python
print(r2python(rscript, pep8=True))

控制台输出

ANTLR runtime and generated code versions disagree: 4.9.1!=4.8 ANTLRruntime and generated code versions disagree: 4.9.1!=4.8 frompython2r_helper import make_tuple

def nb(y=1930):
    debut = 1816
    MatDFemale = matrix(D . Female, nrow=111)
    colnames(MatDFemale) .set(range((debut + 0), 198))
    cly = range((y - debut + 1), 111)
    deces = diag(MatDFemale[:, cly[set(cly) & set(range(1, 199))]])
    return make_tuple(B . Female[B . Year == y], deces)
