Ag5tools cdsapi client error

[howardvanmeer]

Dear David, I am a PhD student at Wagenen University, I came across your Ag5tools Package. I followed all the steps but a get this error massage when I call download function.

Error in cdsapi$Client() : attempt to apply non-function

session_python gives following info python: C:/Users/meer164/AppData/Local/anaconda3/envs/wk_ecmwf/python.exe libpython: C:/Users/meer164/AppData/Local/anaconda3/envs/wk_ecmwf/python36.dll pythonhome: C:/Users/meer164/AppData/Local/anaconda3/envs/wk_ecmwf version: 3.6.15 (default, Dec 3 2021, 18:25:24) [MSC v.1916 64 bit (AMD64)] Architecture: 64bit numpy: C:/Users/meer164/AppData/Local/anaconda3/envs/wk_ecmwf/Lib/site-packages/numpy numpy_version: 1.19.5 cdsapi: C:\Users\meer164\AppData\Local\ANACON~1\envs\wk_ecmwf\lib\site-packages\cdsapi__init__.p

NOTE: Python version was forced by RETICULATE_PYTHON

Can you please help me out? Thanks in advance

Dear Howard,

Could you please check what is returned when you try: reticulate::import("cdsapi")

Also, could you please share the code where you call the ag5_download() function?

Thanks,

David

Just the example from your paper about the tool library(ag5Tools) ag5_download(variable = "2m_temperature", statistic = "day_time_maximum", day = "all", month = "all", year = 2000:2005, path = "C:/Users/meer164/Downloads/ERA5/") I get: reticulate::import("cdsapi")

It should return Module(cdsapi), I think.

Please post what reticulate::conda_list() returns.

[howardvanmeer]

retiulate::conda_list() gives: I made an environment called "wk_ecmwf" following all the steps mentioned on copernicus webpage reticulate::conda_list() name python 1 base C:\Users\meer164\AppData\Local\anaconda3/python.exe 2 wk_ecmwf C:\Users\meer164\AppData\Local\anaconda3\envs\wk_ecmwf/python.exe

I'm sure you already installed cdsapi but could you please check if it works after trying this:

reticulate::conda_install("wk_ecmwf", "cdsapi")

[howardvanmeer]

still giving same error. .cdsapirc file with URL and key is in user/meer164 directory. What else could there be wrong?

Dear David,

I saw you did your PhD at Wageningen University. If we don't manage through these messages, do you think there is someone here at WUR to help me out?

Hi Howard,

I think it could be related to reticulate. Could you please try: 1) Re-install reticulate 2) Re-install cdsapi using reticulate::conda_install(packages = "cdsapi")

I know you created the wk_ecmwf environment for a reason, but perhaps using the r-reticulate default environment would work, which I don't see in your list of environments.

If reticulate/python and the cdsapi are ok you should be able to run this, regardless of ag5tools:

library(reticulate)

cdsapi <- reticulate::import("cdsapi")

c <- cdsapi$Client()

c$retrieve(
  'sis-agrometeorological-indicators',
  list("version" = "1_1",
       "format" = "zip",
       "variable" = "precipitation_flux",
       "year" = "1979",
       "month" = "01",
       "day" = "01"),
  "download.zip")

Please let me know if that works.

I cannot refer to someone in specific at WUR but basically anyone with experience using reticulate could help, I think.

Thanks, David
