Unable to upgrade to latest version of MCMCDiagnosticTools

New to Julia

Hello everyone,

Here is what the software is saying to me :

Can someone explain to me how I can upgrade to the latest version of MCMCDiagnosticTools?

Many thanks.

It’s really useful to format your code with triple backticks ``` to make it legible.

In short, you have MCMCDiagnosticTools in your environment which restricts MCMCChains to versions <=4.14, and you also have Turing in your environment which is restricted to >=0.23.2 by CRRao. Turing@0.23.2 does not allow MCMCChains below version 5 though, so the environment cannot be resolved.

It also looks like you are installing all your packages in the default environment - don’t do this, work with project specific environments instead to minimise incompatibilities like this.

@nilshg Many thanks for your reply.

I have added the ``` around the code as you suggested.

I have another query. I need Turing / CRRao / MCMCChains for my analysis.

On carefully examining my analysis, I do not need MCMCDiagnosticTools.

But now I am curious, how would I fix this if I did needed MCMCDIagnosticTools?

You would need to make a PR to one of the packages to make them compatible - most likely in this case to MCMCChains to allow a more recent version of MCMCDiagnosticTools.

In this specific case as far as I understand CRRao is just a wrapper around GLM and Turing so you could just use the underlying packages rather than CRRao.

Dear @nilshg,

Many thanks for that.
