SyntaxError: f-string expression part cannot include a backslash

[00izquierdoguillem]

When trying to run dadi-cli BestFit after installation I came across the following error:

SyntaxError: f-string expression part cannot include a backslash

The error referred to line 81 of the Stats.py file:

f.write(f"Description\t{'\t'.join(param_names[1:])}\n")

I solved this error by changing this code to:

f.write(f"Description\t{join(param_names[1:])}\n") before running pip install .

It appears that this might not be an issue for users with python version > python3.12, but I suggest changing the code of Stats.py to my suggestion above in order to help users with an older python version.

Hi @00izquierdoguillem, thanks for letting us know! I've done some testing, and I can't recreate the error. What OS and version of Python (python --version) are you running, and what is the full command you are running that caused the error?

Hi @tjstruck! I encountered problems when using dadi-cli while running a simple command:

dadi-cli BestFit --input-prefix My_dataset.InferDM

This is a command I've been using recurrently over the last few months using dadi-cli v0.9.2 and never experienced any problems. However, once I installed the newest version of dadi-cli (by downlading the Github repository) it generated the above error. I didn't try any other commands, but I'm guessing I might have encountered the same error when trying to access Stats.py.

I encountered problems when using Python 3.9.13 and Python 3.11.0 (couldn't manage to install Python 3.12). When I modified the code as explained above I stopped experiencing such issues under both Python versions.

Thanks for your help!
