Neural network Survival Analysis-Error

[drchehidayat]

Hi,
I try to replicate the codes from the article entitles, "Neural Networks for Survival Analysis in R" by @RaphaelS1 . However, I could not finish it due to some error.
First of all, im using Macbook Air M1 and R software for analysis.

Here are the codes and error that I've received
Code:
install_keras(pip = TRUE, install_tensorflow = TRUE)
Error:
ERROR: Could not find a version that satisfies the requirement tensorflow (from versions: none)
ERROR: No matching distribution found for tensorflow
Error: Error installing package(s): "'tensorflow'", "'keras'"

Code:
learners <- c(learners, lrns(c("surv.kaplan", "surv.coxph")))
design <- benchmark_grid(tasks, learners, resampling)
bm <- benchmark(design) -- ERROR
Error: Error: TaskSurv:whas has the following unsupported feature types: factor

I hope @RaphaelS1 or anyone can help me with this problem.

Hey your code seems to suggest the bug might be in survivalmodels. Would you mind reopening this discussion as an issue is RaphaelS1/survivalmodels? And when you do please can you include a reprex if possible with the sessionInfo included
