This issue template serves as the checklist for essential information to most of the technical issues. If the issue is non-technical, feel free to present the information in what you believe is the best form. ## Description (Brief description of the problem in no more than 2 sentences.) ## Environment info (Required) ``` What to do: 1. Download the diagnosis script from https://raw.githubusercontent.com/apache/incubator-mxnet/master/tools/diagnose.py 2. Run the script using `python diagnose.py` and paste its output here. ``` Package used (Python/R/Scala/Julia): fg (I'm using ...) For Scala user, please provide: 1. Java version: (`java -version`) 2. Maven version: (`mvn -version`) 3. Scala runtime if applicable: (`scala -version`) For R user, please provide R `sessionInfo()`: ## Build info (Required if built from source) Compiler (gcc/clang/mingw/visual studio): MXNet commit hash: (Paste the output of `git rev-parse HEAD` here.) 65b258700dda06b0c9d1913ff5aa525beb88438b Build config: (Paste the content of config.mk, or the build command.) ## Error Message: (Paste the complete error message, including stack trace.) ``` src/io/iter_image_recordio_2.cc: In function ?<built-in>?: src/io/iter_image_recordio_2.cc:575:9: error: ?contrast_scaled? may be used uninitialized in this function [-Werror=maybe-uninitialized] ProcessImage<4>(res, &data, is_mirrored, contrast_scaled, illumination_scaled); ^ src/io/iter_image_recordio_2.cc:558:13: note: ?contrast_scaled? was declared here float contrast_scaled; ^ src/io/iter_image_recordio_2.cc:575:9: error: ?illumination_scaled? may be used uninitialized in this function [-Werror=maybe-uninitialized] ProcessImage<4>(res, &data, is_mirrored, contrast_scaled, illumination_scaled); ^ src/io/iter_image_recordio_2.cc:559:13: note: ?illumination_scaled? was declared here float illumination_scaled; src/io/iter_image_recordio_2.cc: In member function ?void mxnet::io::ImageRecordIOParser2<DType>::ProcessImage(const cv::Mat&, mshadow::Tensor<mshadow::cpu, 3, DType>*, bool, float, float) [with int n_channels = 1; DType = float]?: src/io/iter_image_recordio_2.cc:409:13: error: ?RGBA_MEAN[0]? may be used uninitialized in this function [-Werror=maybe-uninitialized] RGBA[k] = (RGBA[k] - RGBA_MEAN[k]) * RGBA_MULT[k] + RGBA_BIAS[k]; ``` ## Minimum reproducible example (If you are using your own code, please provide a short script that reproduces the error. Otherwise, please provide link to the existing example.) ## Steps to reproduce (Paste the commands you ran that produced the error.) 1. build with DEV=1 in config.mk 2. ## What have you tried to solve it? 1. build with DEV=1 passes for commit ffa6e45aad4eeca8e6d27764789cd615d132fcb9 @ptrendx seems this is introduced by #7152 2. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
