ValueError: Configurable 'ExperimentConfig' doesn't have a parameter named 'datasource_spec'.

Just following along the colab notebooks.

Processed the video, trained the model with dataset saved to /content/gdrive/My Drive/nerfies/captures/capture1 and config.gin and checkpoints saved to /content/gdrive/My Drive/nerfies/experiments/capture1/exp1.

For Model and dataset configuration during rendering, the following error occurs:

Loading config from /content/gdrive/My Drive/nerfies/experiments/capture1/exp1/config.gin

I checked config.gin file and ExperimentConfig.datasource_spec is there. I check configs.py and I see datasource_cls instead of datasource_spec - should this be changed?

Similarly, ModelConfig in the colab should be changed to NerfModel?

and I've commented out the following in the generated config.gin as these are not available in configs.py

# NerfModel.use_appearance_metadata = 1
# NerfModel.warp_field_type = 'se3'
# NerfModel.num_warp_freqs = 8

Are you going to update how config.gin is setup in the colab notebook so that gin.parse_config(config_str) works smoothly?

I think that I've found a workaround for this issue.

I was mistakenly running the Nerfies training colab notebook, because this was linked in the "Process a video into a dataset" colab linked from the README. This creates this file: /content/gdrive/My Drive/nerfies/experiments/capture1/exp1/config.gin This config.bin file is not compatible with HyperNeRF_Render_Video.ipynb. For example, it includes ExperimentConfig.datasource_spec, and generally looks very different.

Instead, I tried running the HyperNeRF training colab notebook, which creates the hypernerf_experiments folder. The corresponding config.gin file is compatible with the HyperNeRF_Render_Video.ipynb.
