Check Availability of the pyWitness Engine

Reports whether Python and pyWitness are available without initializing Python by default.

Usage

check_pywitness_deps(
  envname = .pywitness_default_env,
  initialize = FALSE,
  verbose = TRUE
)

Arguments

envname

Name or path of the intended virtual environment.

initialize

Logical. If TRUE, select envname, initialize Python, and import pyWitness. The default performs no initialization.

verbose

Logical. Print a concise status report.

Value

A one-row tibble with environment and engine status, including whether the imported version encodes the audited revision when initialize = TRUE.

Examples

#> pyWitness environment: r4lineups-pywitness 
#> Environment exists: FALSE 
#> Python initialized: FALSE 
#> pyWitness available: FALSE 
#> Audited revision: e726dcfc09423d0e0ff7f46c8e3a711040293eba 
#> No Python process was initialized. Use initialize = TRUE to import the isolated engine.
