Question

当我尝试用简单的python代码主干编织.Rmd文件时，它失败了。但是，当我在[0.0 ... 1.0]包中使用repl_python()函数时，所有python代码都可以在控制台命令行中顺利运行。

键入reticulate时，它返回py_available()。

因此，我认为我的Python配置没有错误。我无法弄清楚我的R Markdown文件出了什么问题。

TRUE

结果证明：

```{r setup}
library(reticulate)
#conda_create("r-reticulate") # I created a new conda environment
#conda_install("r-reticulate", "scipy") # and I installed all python libraries I need.
#conda_install("r-reticulate", "pandas")
#conda_install("r-reticulate", "seaborn")
use_condaenv("r-reticulate")
py_module_available('pandas')
```

```{python}
import numpy as np
import seaborn as sns
from scipy.stats import f
from scipy.stats import boxcox

r = f.rvs(30, 30, size=500)
np.random.seed(1234) 
transformed,fitted_lambda = boxcox(r)
print('lambda=',fitted_lambda)
sns.distplot(r, rug=True,color='green')
sns.distplot(transformed, rug=True)
```

P.S。当我使用Quitting from lines 34-37 (reticulate.Rmd) Error in py_call_impl(callable, dots$args, dots$keywords) : ImportError: IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE! Importing the numpy c-extensions failed. - Try uninstalling and reinstalling numpy. - If you have already done that, then: 1. Check that you expected to use Python3.8 from "C:\PROGRA~1\R\R-36~1.1\bin\x64\Rterm.exe", and that you have no directories in your PATH or PYTHONPATH that can interfere with the Python and numpy version "1.17.3" you're trying to use. 2.

我尝试了conda_install("r-reticulate", "libraryname")的CRAN和开发版本，但都失败了。

我的R环境是：

reticulate

sessionInfo()

我的经验是，如果您遇到相同的问题，请使用git并回滚到以前的提交版本，该问题将得到解决。：D

git reset
