Rstudio Notebook (rmarkdown) running python: describe not shown

问题

I am runing some python chunks in a Rstudio notebook, which include reading a csv file and printing basic statistics. I could not find the way to print the statistics (describe()) as an output. Here is the code:

```{python, engine.path = '/home/user/anaconda3/bin/python3'}
   import pandas
   data_py = pandas.read_csv('/home/user/datafiles/data.csv', sep= ';')
```

```{python, engine.path = '/home/user/anaconda3/bin/python3'}
   data_py.describe(include='all')
```

NO output printed. I also tried:

 ```{python, engine.path = '/home/user/anaconda3/bin/python3'}
    print(data_py.describe(include='all'))
```

and

 ```{python, engine.path = '/home/user/anaconda3/bin/python3'}
    summary = data_py.describe(include='all')
    print(summary)
```

with no success. Any help?

I had the same problem and found out the code you wrote works if you put in your .Renviron file:

PYTHONPATH=/home/alex/anaconda2/lib/python2.7/site-packages/

Change the path to your site-packages (or where packages are)

{python} import pandas data_py = pandas.read_csv('data.csv', sep= ';') data_py.describe(include='all') summary = data_py.describe(include='all') print( summary)
