Hi All,
I’m struggling to get anything out of my notebooks. I’ve tried lots of different variations and examples from the forums but can’t seem to find one which works for me.
I have setup a simple input. 60 minutes of data into data.csv
## I have setup a simple Notebook file. Code is:
import os
import pandas as pd
input\_dir = os.path.join(os.environ[‘INPUT\_DIR’])
dataset = pd.read\_csv(input\_dir, ‘data.csv’)
–
My notebook debug is:
–

Any advice would be appreciated.
I have managed to get some other notebooks working on my local machine. However porting to Losant is my issue.
Many thanks,
Chris

Hi @ChrisGM,
We here at the Losant Forums are happy to help with Losant Notebook problems surrounding accessing data and performing analysis. Our expertise lies in the Losant Platform, so we recommend checking out the [Jupyter Blog](https://blog.jupyter.org/), the [Jupyter Live Chat](https://gitter.im/jupyter/jupyter), or posting on the [Jupyter Discourse Forum](https://discourse.jupyter.org/) for challenging problems within the Jupyter Notebook and help writing Notebook Code. In this case, it looks as though this snippet will cause some issues:
```auto
input_dir = os.path.join(os.environ[‘INPUT_DIR’])
dataset = pd.read_csv(input_dir, ‘data.csv’)
```
In this first line, you are not joining any values, which is likely resulting in this error; I will update the documentation to fix this snippet. I would recommend rewriting this to:
```auto
dataset = pd.read_csv(os.path.join(os.environ['INPUT_DIR'], 'data.csv'))
```
Please let me know if this does not provide a resolution,
Julia
