无法读取 TDMS 文件（'TdmsFile' object 没有属性 'xxx'）

Question

I have trouble reading my tdms file from LabVIEW.

1, Read my file from my path. It is ok to load it at this point.

tdms_file = TdmsFile('/path/to/Env16-05-30-2021.tdms')

2, Successfully see the group property:

tdms_file.groups()

It returned:

[<TdmsGroup with path /'Measured Env Time'>,
 <TdmsGroup with path /'Measured Env Data'>]

3, I can not access to group channels in one of my group:

tdms_file.group_channels('Measured Env Time')

It returned:

'TdmsFile' object has no attribute 'group_channels'

4, I already know my group_channels name and try to access it

time = tdms_file.object('Measured Env Time', 'Time').data

It returned:

'TdmsFile' object has no attribute 'object'

Does anyone have any idea? Thanks!

Since you did not post what python package you are using to read the TDMS file I will assume you are using the latest version of npTDMS .

Looking at its documentation it seems you should access the channels of a group via

group_channels = tdms_file[group_name].channels()

Or if you already know the group and the channel you can just

channel = tdms_file[group_name][channel_name]
