still can't run with mac

[YushuShi]

I installed python and classo but it seems not working when I run the example in mac??

fit <- trac(ztr, ytr, A = sCD14$A, min_frac = 1e-2, nlam = 30)
Error: Python module classo was not found.

Thanks for the update; can you try to load reticulate first, then force the Python environment where you installed c-lasso, and then run the vignette?

library(reticulate)

use_python("YOUR PYTHON PATH WITH CLASSO",required = TRUE)

library(trac)
...

c-lasso depends on the python package: numpy, scipy, matplotlib and pandas. Installing these packages helped in my case.
