Elastic Net Regression in R

[prateeksasan1]

Hi,

I just downloaded the h2o4gpu package for R 4.0.2 and tried running the examples. While running the elastic net regression, i got the following error :

System Information :

R : 4.0.2
Cuda : 10.0.130
Python: 3.6
packageVersion(h2o4gpu): 0.3.2

Code :

train <- read.csv("https://s3.amazonaws.com/erin-data/higgs/higgs_train_10k.csv")
test <- read.csv("https://s3.amazonaws.com/erin-data/higgs/higgs_test_5k.csv")

Create train & test sets (column 1 is the response)

x_train <- train[, -1]
y_train <- train[, 1]
x_test <- test[, -1]
y_test <- test[, 1]

model_enc <- h2o4gpu.elastic_net_classifier() %>% fit(x_train, y_train)

Error :

Error in py_call_impl(callable, dots$args, dots$keywords) :
ImportError: cannot import name 'signature'

You need to substitute line 1232 in elastic_net.py with
from funcsigs import signature
