Works when commit 64c5cdf is reverted, with the exception of removing point.data[0].numpy() in favour of point.data.numpy() on line 90. Check if it works after changes. The rest of it works perfectly so I'll push if the change works

[adityapentyala]

also, could you add tqdm to the env file? had to install that but again it might be a problem with only my env

[shailx383]

removed tqdm as it is not required

[adityapentyala]

line 90 still throws an error when only point.data is written. code runs perfectly with point.data.numpy()
