Hi,
trying to load and transform png images using load_image function based on one of torchvision's vignettes
load_image <- function(path) { x <- png::readPNG(path) %>% transform_to_tensor() %>% transform_grayscale(num_output_channels = 1) %>% transform_resize(c(105, 105)) x <- x[newaxis,..] }
but getting this error:
Error in `not_implemented_error()`: ! not implemented for torch_tensor • not implemented for R7
