Got blank heatmap when running evaluation code #30

Closed kungfrank closed 5 months ago

kungfrank commented 6 months ago

Hi,

I tried to run the eval.sh for evaluation, but I found the result is all blank using the provided pre-trained autoencoder (download from 'pretrained_model/ckpt') and language-embedded Gaussian splat (download from 'pretrained_model/output').

I also tried to follow the process.sh file to self-train the autoencoder and language-embedded Gaussian splat, but the heatmaps are still blank.

All images under LangSplat/eval_result/teatime/***/heatmap are looking like this apple_2

However, the renders I got are all looking good: LangSplat/output/teatime/teatime_1/train/ours_None/renders/00000.png 00000

Does anyone get the evaluation work or face the same problem as me?

Problem solved. I realized that I accidentally changed the original code, which now works fine. Sorry for bothering.
