Question

The following code for data acquisition gives the below error

import nidaqmx
with nidaqmx.Task() as task:
    nidaqmx.Task.ai_channels.add_ai_voltage_chan("Dev1/ai0")
    task.read()

Do you know what is the reason and how to fix it? Thanks, Cheers!

Run this pip install nidaqmx command from cmd to install module.

Answer 2

There are two different software packages you have to install:

• The Hardware driver (NI-DAQmx)
• The software driver package (Python package nidaqmx)

You are missing the Hardware driver. You can download it here.
