Did you update mlr3proba? remotes::install_github('mlr-org/mlr3proba')
Thank you very much for your reply, I have used remotes::install_github('mlr-org/mlr3proba') to update mlr3proba, the mlr3proba verson is 0.4.2.9000 . when I run the code ,the error "Error in as.Distribution.matrix(cdf, fun = "cdf", decorators = c("CoreStatistics", : 'obj' must have column names This happened PipeOp surv.loghaz.tuned's $train())' still exist. Do you know how to solve it ? Thanks!!!
I am having the same problem .. benchmark runs just fine and then stops out of nowhere:

Hello, sorry for the lack of a prior greeting/introduction :) I am currently working an a ML solution fora survival analysis on medical data. I am currently exploring mlr3 and am very excited about it. I based my analysis on your examples and on some reading I did in the mlr3book.
The above mentioned error also occurs when I execute resample instead of benchmark
rr <- lapply(learners,
function(x)
resample(task, x, resampling))
any ideas?
Hi @Toxgondii and @pcstudy2019
Try running remotes::install_github('mlr-org/mlr3extralearners#147'), then restart your session and try again
Thank you very much for your reply, I have used' remotes::install_github('mlr-org/mlr3extralearners#147') 'and 'remotes::install_github('mlr-org/mlr3pipelines')' to update packages, the error ''obj' must have column names' was disappeared ,but new errors :
'Error in FUN(newX[, i], ...) :
identical(order(.x), seq(ncol(x))) is not TRUE
This happened PipeOp surv.coxtime.tuned's $predict()'
appeared.
Can you help me with this? thank you very much!!!
Ah you might now need remotes::install_github('RaphaelS1/survivalmodels')
Thank you very much for your reply, I used remotes::install_github('RaphaelS1/survivalmodels') there still 'Error in FUN(newX[, i], ...) : /
/ identical(order(.x), seq(ncol(x))) is not TRUE/This happened PipeOp surv.loghaz.tuned's $train()' .
I did not know why? thank you very much!!!
Hi Raphael, I'm encountering the same error message when following your very helpful walk-through on Towards Data Science.
I've updated the packages suggested (through remotes::install_github('mlr-org/mlr3extralearners#147') and remotes::install_github('mlr-org/mlr3proba')) and the error persists - see below (with some of the info lines removed to save space). This occurs on both my Windows 10 laptop on a Linux desktop. The other thing to add is that the error occurs after a variable number of iterations/learner applications.
If you have any suggestions I'd be very grateful! Cheers.

Thanks! I know where the error is caused but annoyingly I need to fix it on a computer I don't have access to right now. I will try to fix it on Friday if not before. Sorry about this!
But, one fix for now is simply to install all packages to the versions that are listed in the tutorial:
- mlr3benchmark (v0.1.2)
- mlr3extralearners (v0.3.5)
- mlr3pipelines (v0.3.4)
- mlr3proba (v0.3.2)
- mlr3tuning (v0.8.0)
- survivalmodels (v0.1.7)
As well as distr6 (v1.5.6)
Hi @RaphaelS1, Thanks for your help, based on your suggestion for keeping all packages match related versions.
library(mlr3benchmark)
## create mlr3benchmark object
bma <- as.BenchmarkAggr(bm,
measures = msrs(c("surv.cindex", "surv.graf")))
## run global Friedman test
bma$friedman_test()
This is worked.
BUT the later step is error
## load ggplot2 for autoplots
library(ggplot2)
## critical difference diagrams for IGS
autoplot(bma, meas = "graf", type = "cd", ratio = 1/3, p.value = 0.1)

Please help me to check this error, best.
HI @jianguozhouzunyimedicaluniversity as the error says "Package PMCMR required for post-hoc Friedman tests.
Traceback:". You need to install the missing package
install.packages("PMCMR")
hi @RaphaelS1 thanks for your help.
I installed the PMCMR package.
but still, have a new error, I guess we need to confirm the corrected version.

Hi @RaphaelS1,
I've only just been able to revisit this and can confirm that installing the older versions of the packages you indicated (mlr3benchmark (v0.1.2), mlr3extralearners (v0.3.5), mlr3pipelines (v0.3.4), mlr3proba (v0.3.2), mlr3tuning (v0.8.0), survivalmodels (v0.1.7), distr6 (v1.5.6)) also works for me and allows the walkthrough to run. Thanks for your help here and for the package itself!
(I can also reproduced the error that @jianguozhouzunyimedicaluniversity has indicated -
autoplot(bma, meas = "graf", type = "cd", ratio = 1/3, p.value = 0.1)
Error: 'posthoc.friedman.nemenyi.test.default' is defunct.
Use 'PMCMRplus::frdAllPairsNemenyiTest' instead. )
Dear all, @RaphaelS1

I updated all related packages but still got “ 'Error in FUN(newX[, i], ...) : /

Finally fixed! Please install the latest versions of mlr3extralearners, mlr3proba and survivalmodels from GitHub and latest versions of distr6 and param6 from CRAN:

@RaphaelS1 Thank you very much, Now it works in my MacBook.
@RaphaelS1 Thanks so much! The previous error disappeared after I updated the packages. But I just got a new error as here: "

Could you please help me with that or shed some lights on it? Thanks in advance!
Are you using your own data? It is saying that at t=0 there is an event (death or censoring). You should manually set that to a different time (e.g. 0.001) or remove the observation
Hi @RaphaelS1, Yes I am using my own data, I checked my data and all my time are >0. I wonder if you have any suggestions about the error message "Survival probabilities must be (non-strictly) decreasing" above. Thanks in advance!
Ah apologies I saw the warning not the error. The error is saying that the predictions from your model are not valid survival probabilities. Unfortunately without access to your data I can't tell if the error is in my software, your code, or your data. I suggest you open an issue in the survivalmodels repo so we can figure it out properly
Hi Raphael, first thanks for you work. It just what I needed. However, I'm encountering the error as follows. Do you know what's the reason? Thanks!

Error in py_call_impl(callable, dots$args, dots$keywords) :
RuntimeError: CUDA error: unspecified launch failure
CUDA kernel errors might be asynchronously reported at some other API call, so the stacktrace below might be incorrect.
For debugging consider passing CUDA_LAUNCH_BLOCKING=1.
Compile with TORCH_USE_CUDA_DSA to enable device-side assertions.
Thanks Raphael, I fixed this problem by upgrading the ''mlr3proba" package. However, this is another error from the "coxtime" model as follows.
Error in py_call_impl(callable, dots$args, dots$keywords) :
AttributeError: 'Series' object has no attribute 'iteritems'
This happened PipeOp surv.coxtime.tuned's $train()
When I remove the "coxtime" model from the learners list, everything is OK.
Great! Strange I've never seen that error before... Looks like it's in the underlying {pycox} implementation. Maybe try reinstalling pycox?
Hello, sorry to bother you. I have updated the distr6 package (1.6.2) and mlr3 package (0.13.0) to the latest, but the above problem still exists. ("Error in as.Distribution.matrix(cdf, fun = "cdf", decorators = c("CoreStatistics", 👍 'obj' must have column names")
Do you know how to solve it ? Thanks!!!
