Open amiltonwong opened 6 years ago

amiltonwong commented 6 years ago

Hi, @charlesq34 ,

I completed the dataset preparation step. However, when I run python train/provider.py to visualize the training data. I got the window holding... pic. After I press the "enter" in the terminal. A few maiya windows prompts out. But they are freezed. How could I operate the maiya windows for visualizing the pointclouds ?

THX!

Hi @amiltonwong are you running with ssh session? there might be some issue with remote access.

if you are running locally, it might take a few seconds to display the point clouds.

Hi @amiltonwong ,

I also had some issues with mayavi displaying the pointcloud. Besides this: Use OpenCV version 2.4.x Make sure to install the package PySide along with PyQt4,

I still had the issue of the freezing window. I was able to get rid of it by exporting these variables: export ETS_TOOLKIT=qt4 and export QT_API=pyqt

I hope it helps others!

If you are using Jupyter Notebook to visualize the Point Cloud, you will have some issue
