[ICCV 2021] Aligning Latent and Image Spaces to Connect the Unconnectable

alis's Issues

Why instance_norm is False?

I just wonder why the instance_norm term in the configuration file is False even though the normalization is done in equation 6 in the paper ? I think I am missing somehting.

Do you have any suggestion on how to implement this model for 2D infinite generation?

I was wondering if you have any suggestion on how to implement the code for 2d image generation such and satellite images or 3D panorama images.

How to resume training from provided checkpoint?

I couldn't locate an option to specify the pretrained checkpoint so I specified it in training/training_loop.py in resume_pkl field.
After running the training job, I encounter this error:

-- Process 0 terminated with the following error:
Traceback (most recent call last):
  File "/opt/conda/envs/alis/lib/python3.8/site-packages/torch/multiprocessing/spawn.py", line 19, in _wrap

    exec(src, module.__dict__) # pylint: disable=exec-used

ImportError: attempted relative import with no known parent package

What is the correct way to specify a pretrained checkpoint or resume from an existing one?

About reproducing

Hi,

Thank you for your great work! Have you ever cleaned the lhq dataset? I used the lhq_1024_jpg dataset to reproduce the effect, and the FID can only reach 9. I tried to fine-tune on the open source model, but the initial FID was as high as 24.

Best,
JiKun

Comments / Clarification of Generate.ipynb

Thank you for the great project!
I'd like to ask for some clarification of how the generation process works in the generate.ipynb notebook. A bit of guidance / code comments in the third cell (starts with "num_frames") would be most appreciated. In particular, I'd like to:

• Explicitly define the starting vector of an inference (rather than starting from a random location).
• More carefully control the magnitude of each "shift" that produces the segments of the panorama. Where can I adjust how "far away" in latent space each step is?

I'm asking for these clarifications because I'd like to make a different sort of animation. Rather than panning across a long panoramic strip, I'd like the strip as a whole to animate across a "latent walk" (something like shown here, but in which the animation could be of arbitrary width).

Again, thank you for an excellent project, and for any guidence.

Appendix file

Hi,
Where to download your appendix file?

Feedback from running inference on Win10

I'm on conda 4.9.2, Windows 10 64bit

In case anyone finds it useful, then:
I had to run
conda install -c anaconda cmake
To get CMAKE into the environment, however, for some reason pip has failed to install ninja from source.

So after activating the environment, I did the following steps which did not get executed due to the ninja build fail:
conda install ninja==1.10.0
conda install tqdm==4.59.0 gitpython scikit-learn
pip install gpustat
pip install tensorboard==2.4.1
pip install -e .
pip install omegaconf click

I was then able to run the inference notebook and generate a lovely panoramic image

To generate the video, I had to first run:
conda install -c conda-forge opencv
To get opencv into the environment

The video was then generated and it looks beautiful.
Cheers!

Dataset

Any plans to upload the dataset? Thanks.

Colab?

Any way to run this in colab?

Is Python 3.8.5 necessary?

Thanks for your interesting work!

When running your generate.ipynb on Linux, I am trapped in a messy dependency issue.
By reviewing your environment specification, I notice your Python version is quite high (for now):

alis/environment.yml

Line 6 in 9699eba

- python=3.8.5

For example, when I install opencv via conda, I get:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - opencv -> python[version='>=2.7,<2.8.0a0|>=3.5,<3.6.0a0|>=3.6,<3.7.0a0|>=3.7,<3.8.0a0']

Your python: defaults/linux-64::python==3.8.5=h7579374_1

If python is on the left-most side of the chain, that's the version you've asked for.
When python appears to the right, that indicates that the thing on the left is somehow
not available for the python version you are constrained to. Note that conda will not
change your python version to a different minor version unless you explicitly specify
that.

I wanna know if this Python version is necessary since I would like to downgrade it.

BTW, there's no opencv specified in your environment.yml.

Continuing training from the last snapshot

Is there a way to continue the training from the latest saved pickle?

Issue while launching generate.py

Hello.

THanks for your code. When i'm trying to launch generate file i'm getting this error:

As a clarification, generate.py is just your pynb copied to regular python script file, it's just easier for me.
Tried to search for this nvcc fatal : Unknown option '-generate-dependencies-with-compile' but currently got no clue.

I'm using pytorch 1.8, cuda 10.1, Ubuntu 20. THanks in advance for the help.
