lichen11 opened a new issue #13139: Normalize pixels to [0,1] using im2rec or reassign values to rec files URL: https://github.com/apache/incubator-mxnet/issues/13139 I want to normalize the pixel values into [0, 255] without reading the images, normalizing them and re-saving them as jpeg. I used the im2rec API in R and notice there is no value normalization in this API. Then I tried reassign values to the rec files as follows: val = mx.io.ImageRecordIter( path.imgrec = val_data, batch.size = batch_size, data.shape = data_shape, rand.crop = FALSE, rand.mirror = FALSE) val$reset() val$iter.next() val_data = val$value()$data val_data = as.array(val_data) val_data = val_data/255 val$value()$data = val_data I got the error below Error in val$value()$data = val_data : invalid (NULL) left side of assignment Is there another way to normalize the images by 255 in mxnet R? Thank you!
