I’m running Jupyter on windows and I’m struggling to define the environment variables INPUT\_DIR and OUTPUT\_DIR before launching the notebook.

Any guidance here?

Hi @Lars_Andersson,

[This forum post](https://forums.losant.com/t/setting-input-dir-and-output-dir-to-show-locally-on-os-environ/1870) has instructions on setting your environment variables for Windows. Please let me know if you have an questions 😄

Thanks!

Correction, it now works when executing the Notebook locally, but not when running on Losant.  
Do I need to modify the definition of the INPUT\_DIR and OUTPUT\_DIR before I upload the .ipynb file?  
The execution log shows me Jupyter error, and the first 3 lines shows this:  
[NbConvertApp] Converting notebook /tmp/input.ipynb to notebook  
[NbConvertApp] Executing notebook with kernel: python3  
[NbConvertApp] ERROR | Error while converting ‘/tmp/input.ipynb’

Never mind, as soon as I commented out the local IN/Out directories, it worked.
