image_load : 'float' object cannot be interpreted as an integer

[danli349]

Hello:

library(keras3)
img <- image_load("book_images/flamingo.jpg", target_size = c(224, 224))

How should I solve this problem? Thanks

'float' object cannot be interpreted as an integerTraceback:

1. do.call(keras$utils$load_img, args)
2. (structure(function (path, color_mode = "rgb", target_size = NULL, 
 .     interpolation = "nearest", keep_aspect_ratio = FALSE) 
 . {
 .     cl <- sys.call()
 .     cl[[1L]] <- list2
 .     call_args <- split_named_unnamed(eval(cl, parent.frame()))
 .     result <- py_call_impl(callable, call_args$unnamed, call_args$named)
 .     if (py_get_convert(callable)) 
 .         result <- py_to_r(result)
 .     if (is.null(result)) 
 .         invisible(result)
 .     else result
 . }, class = c("python.builtin.function", "python.builtin.object"
 . ), py_object = <environment>))(path = "book_images/flamingo.jpg", 
 .     target_size = c(224, 224))
3. py_call_impl(callable, call_args$unnamed, call_args$named)
4. stop(structure(list(message = "TypeError: 'float' object cannot be interpreted as an integer\nRun `reticulate::py_last_error()` for details.", 
 .     call = py_call_impl(callable, call_args$unnamed, call_args$named)), class = c("python.builtin.TypeError", 
 . "python.builtin.Exception", "python.builtin.BaseException", "python.builtin.object", 
 . "error", "condition"), py_object = <environment>))

Thanks for the bug report, this will fixed shortly.

You can workaround for now by casting target_size to integer:

image_load(image_path, target_size = as.integer(c(224, 224)))
# or 
image_load(image_path, target_size = shape(224, 224))

@t-kalinowski It works, Thanks a lot
