Q&A
This page collects answers to some frequently-asked questions.
- No GPU Usage
- cudaSuccess (2 vs. 0) out of memory
- waifu2x-caffe-cui.exe returned non-zero exit status 1
Q: There doesn't seem to be any GPU usage
A: Go into the GPU page in task manager, and switch one of the views to "Cuda". Now you should be able to see the GPU working hard. If Cuda doesn't seem to be working, it might be a bug. You may then choose to open an issue.
Q: What's this error Check failed: error == cudaSuccess (2 vs. 0) out of memory?
A: It's most likely that you're running too many threads. Try reducing the amount the threads.
Q: waifu2x-caffe failed and the error reads "blabla returned non-zero exit status 1". What's going on?
A: waifu2x-caffe is based on CUDA and cuDNN. It will, therefore, only work on NVIDIA GPUs. If waifu2x-caffe fails without any progress being made, then try the following:
- Make sure that you have an NVIDIA GPU
- Update your GPU driver (regular GeForce driver will do)
- Make sure you have Microsoft Visual C++ Redistributables 2015 installed
If Video2X still fails, then feel free to open an new issue.
