R studio中的reticulate和导入python模块的问题

Question

我正在尝试在r studio中运行网格化和导入python模块(特别是R-markdown)。R代码块似乎完成了预期的工作(即安装python模块)，并且似乎没有产生任何错误，但是python代码块似乎没有完成预期的工作(即导入已安装的包)。它不会产生任何输出(或错误)，这有点奇怪。

我尝试了新安装的reticulate，使用了新安装的R Studio的devtools版本，并使用了完整的conda路径而不是名称，但似乎都不起作用。我不知道出了什么问题。我也已经在stackoverflow中搜索了各种答案，并尝试了各种建议，但似乎都不起作用)。此外，我还安装了miniconda和python ( python包和脚本运行得很好)。如果有人能帮上忙，那就太好了。

(对格式表示歉意，最后的反引号表示代码块的末尾没有正确显示)

## R code chunk

```{r}

library("reticulate")

#devtools::install_github("rstudio/reticulate")

conda_create("my_project_env")

py_install(packages = c("numpy","pandas","scikit-learn","matplotlib","seaborn","statsmodels"))

py_install(packages = c("IPython"))

# Either of these seem to "work" for installation

#conda_install(packages = c("numpy","pandas","scikit-learn","matplotlib","seaborn","statsmodels"))

#conda_install(packages = c("IPython"))

conda_list()

use_condaenv("my_project_env")

The python code chunk below seems to "run" but does not produce any output or errors (such as the python module could not be found) and I am unable to use the modules.

Python代码块

    ```{python}

    # Main packages
    import pandas as pd
    import numpy as np
    import matplotlib.pyplot as plt
    import seaborn as sns

似乎解决方案是以以下方式在r studio代码块中运行导入：

library("reticulate")
conda_create("my_project_env")
py_install(packages = c("numpy","pandas","scikit-learn","matplotlib","seaborn","statsmodels"))
conda_list()
use_condaenv("full_path_to_python_for my_project_env")
py_run_string('import numpy as np')
py_run_string('import pandas as pd')
py_run_string('import matplotlib.pyplot as plt')
py_run_string('import seaborn as sns')

在那里，我可以在python代码块中运行python函数，而不会出现问题。
