CSP Error "float() argument must be a string or a real number, not 'tuple'

Analysis Version 3

Dear all,

The CSP module is currently not working for me. When I click on ‘Fetch and Compute’, the following error message appears in the terminal:

INFO : Fitting started (ExperimentAnalysisGuiSettingsPanel._fitAndFetchOutputData:482)
TypeError: float() argument must be a string or a real number, not ‘tuple’

The above exception was the direct cause of the following exception:

ValueError: setting an array element with a sequence.

This also occurs when I use projects that I have already fitted previously. Is this a general problem, or could it be due to incorrect installation?

Thank you in advance,
Jelena

Hi Jelena,

we don’t have any problems with this here, so it is most likely linked to your projects. Could it be that you have removed some of the Collections or other data from your projects or something like that?

I would recommend trying to go through the full process of Setting up the Input Collection and Input Data Table again before trying the Fetch and Compute. Or if you like you can send us one of your projects (email to support@ccpn.ac.uk) and we’ll take a look at what might be going on there.

Hi Vicky,

Many thanks for the quick reply.
I went through the full process, but it does not help. I sent you an E-Mail with one of my projects.

Many thanks in advance!

Hi Jelena,

this is really strange. I have just taken a look at this and I had no problems fitting the data at all - no errors or anything when I opened your project and clicked on Fetch and Compute. I have sent the project back to you, so I hope you can open it okay. Some of the fits aren’t very good, but without the spectra it is obviously hard for me to know what is going on with the actual data.

Are you definitely up-to-date with all the latest updates? (Go to Help / Check for Updates).
