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 Notebook 中,我现在想从先前创建的 conda 环境中运行该脚本。
我尝试过:reticulate::use_condaenv("pathfinder_example_proj_env", required = TRUE)
reticulate::source_python("../python/python_model.py")
但我遇到了以下错误:
Error in py_run_file_impl(file, local, convert) : ImportError: No module named feather
当我检查reticulate正在使用的Python版本时,得到以下结果:
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()检查可用版本。
reticulate::py_discover_config()

如您所见,虚拟环境已列出。我只是不确定如何使用它。
