When i try uploading data from csv to edge impulse its not allowing me to add more rows on CSV .
Screnshoot the issue so that we can understand it well
Hello @Rishab96 ,
Can you make sure to add a constant timestamp increase?
Feel free to share the first top rows of your CSV file so I can have a better understanding of your issue.

Louis
Thanks louis for support . But i found the why the error occured and was able to find the solution for it.
This was the kind of data that i was uploading . Why edge impulse does not support more than two rows in a csv ??
Hello @Rishab96,
You can have a look at Importing CSV data - Edge Impulse API
Edge Impulse requires CSV data to be stored in a particular format. You’ll need to create one CSV file per sample (e.g. a machine with a fault state). The first row should be a header describing the sensor axes, and each row should be a single reading at a particular time. For multi-axis, time-series data, the first column must be a timestamp. For example, this is data from an accelerometer:
timestamp,accX,accY,accZ
0,4.220828473773600,1.8800472920291100,-16.89228981323240
16,4.471770735278730,2.0017025177553300,-17.887080018505500
32,4.31928972478658,2.4953566802978500,-18.926163539013300
48,4.648792312787470,2.958335718591510,-18.5336641043514
64,4.773739711926880,2.719663740594690,-18.800019623565700
80,4.653879991315310,2.6865938301637800,-19.98305510341230
For a single, multi-axis reading (i.e. something that is not time-series data), you can omit the timestamp. Note that you must have 1 header row and only 1 data row. This is an example from a single, triple-axis accelerometer:
accX,accY,accZ
4.220828473773600,1.8800472920291100,-16.89228981323240
I tried import the csv in above format where timestamp is there in first column but again getting the error this way : For CSV files without a timestamp column, need exactly one line with values (but found 4)
Hello @Rishab96,
You need to put “timestamp” instead of “Timestamp”, will ask our core engineers to add this exception, you’re not the only one to encounter this issue.
However, I can see that your timestamp increase is not constant which will lead to another issue.
Make sure to have a constant frequency before uploading your CSV.

When i upload the csv with multiple rows it is accepting such file but the length of the sample on edge impulse is zero .
Length of the sample is zero .
Hello @Rishab96,
The timestamp is in millisecond, that is probably why. We round the length in the studio for the display.
Best,
Louis
@louis One issue i facing is with split the data sets .Actually i am not able to split the data sets that i have captured.
Hello @Rishab96,
Can you share your project ID please so I can see what goes wrong?
Have you clicked on “+Add Segment”?
