Error when import radical.analytics

[iparask]

I am using a Jupiter notebook to import radical.analyitcs and I am getting the following error:

Would it make sense to specify the path the logger writes as ./?

[andre-merzky]

I think the problem is that your workdir is / - the default location is ./ already, so specifying ./ as path will result in the same error.

So this error happened only with the Jupyter notebook and not when I tried to import it through python interpreter. My path was not / fortunately!

I made the following change locally and it worked:

logger = ru.Logger('radical.analytics', path=os.getcwd())

It may have to do with how a notebook launches on a Mac.

[andre-merzky]

The default log dir is set here - maybe $PWD is not set in your shell env?

@iparask I do not have that issue on Mac with notebooks.

[mturilli]

@iparask should we close this or do you still have that issue?
