tfe_enable_eager_execution

0th

Percentile

Enables, for the rest of the lifetime of this program, eager execution.

If not called immediately on startup risks creating breakage and bugs.

Usage
tfe_enable_eager_execution(config = NULL, device_policy = c("explicit",
  "warn", "silent"))
Arguments
config

(Optional) A tf$ConfigProto() protocol buffer with configuration options for the Context. Note that a lot of these options may be currently unimplemented or irrelevant when eager execution is enabled.

device_policy

(Optional) What policy to use when trying to run an operation on a device with inputs which are not on that device. Valid values: "explicit": raises an error if the placement is not correct. "warn": copies the tensors which are not on the right device but raises a warning. "silent": silently copies the tensors. This might hide performance problems.

Details

After eager execution is enabled, operations are executed as they are defined and tensors hold concrete values, and can be accessed as R matrices or arrays with as.matrix(), as.array(), as.double(), etc.

library(tensorflow)
tfe_enable_eager_execution()

# create a random 10x10 matrix
x <- tf$random_normal(shape(10, 10))

# use it in R via as.matrix()
heatmap(as.matrix(x))
