我使用终端创建了一个conda环境:

conda create --name pathfinder_example_proj_env python=3.6 feather-format=0.4.0 statsmodels=0.9.0


我还创建了一个简单的python脚本

import feather
import pandas as pd
import statsmodels.api as sm

print("Done")


在R笔记本中,我现在想在我之前创建的conda环境中运行该脚本。

我试过了:

reticulate::use_condaenv("pathfinder_example_proj_env", required = TRUE)
reticulate::source_python("../python/python_model.py")


但是我收到以下错误:

Error in py_run_file_impl(file, local, convert) : ImportError: No module named feather


当我检查python网状版本是否使用时,我得到:

reticulate::py_config()

python:         /usr/bin/python
libpython:      /System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/config/libpython2.7.dylib

我使用py_discover_config()检查了可用版本

reticulate::py_discover_config()

如您所见,列出了虚拟环境。我只是不确定如何使用它。

我已经阅读了网状网站上的所有文章:
https://rstudio.github.io/reticulate/index.html

我还在Github上找到了几个线程:
https://github.com/rstudio/reticulate/issues/1
https://github.com/rstudio/reticulate/issues/292

最佳答案

我在这里找到了解决方案:https://community.rstudio.com/t/reticulate-source-python-and-exec-problems/7386/6

在安装了reticulate的开发版本(devtools :: install_github(“ rstudio / reticulate”)之后,reticulate将按预期使用conda环境。

如果其他人遇到此问题,则保留此帖子。
