Missing dependency definition - neither a requirements.txt nor a environment.yml

Hi there,

May I kindly ask you to add a requirements.txt or environment.yml (with the later being prefered)? I am trying to get your code working and am running into multiple dependency issues, such as:

• module not found errors for at least three packages, e.g., kornia
• ImportError for inplace_abn, which might indicate an incompatible PyTorch version (ImportError: /mvsnerf/conda-env-py37/lib/python3.7/site-packages/inplace_abn/_backend.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZNK2at6Tensor3addEN3c106ScalarES2_)

Highly appreciated if you run something like conda env export --file environment.yml from within the active conda environment and add the file to the repository.

Thanks a lot!

Thanks @hengfei-wang for the tip. Thats problem with inplace_abn come from different cuda version of the system and cuda version of pytorch.

I tried to install pytorch + cudatoolkit==11.3 via conda, but in jupyter i had torch.cuda.is_available() == False

After installing all with pip works like a charm.

My installation process:

conda create -n mvsnerf python=3.8
conda activate mvsnerf
pip install torch==1.10.1+cu113 torchvision==0.11.2+cu113 torchaudio==0.10.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html
pip install pytorch-lightning==1.3.5 imageio pillow scikit-image opencv-python configargparse lpips kornia warmup_scheduler matplotlib

Installing inplace_abn from source

git clone https://github.com/mapillary/inplace_abn.git
cd inplace_abn
python setup.py install

Dear authors (@apchenstu), please check your repository and notebooks before you publish it, a lot of imports are missed, variables aren’t initiated, no dependencies file and full installation requirements. Running just single file become challenging!

Well, I used pip install pytorch-lightning==1.3.5 inplace_abn imageio pillow scikit-image opencv-python configargparse lpips kornia==0.5.11 warmup_scheduler to install packages. But I got ‘The CUDA version(11.5) detected is not the one used to compile pytorch(10.5)’ error when installing inpalce_abn. Sorry, I can’t remember exact output message. I guess pytorch-ligntning installs one version of torch compiled by CUDA 10.2 and inplace_abn detects this version and tries to use it. But it found the local cuda version dismatch with torch version, so it reports the error. I reinstalled pytorch using pip3 install torch==1.10.1+cu113 torchvision==0.11.2+cu113 torchaudio==0.10.1+cu113 -f https://download.pytorch.org/whl/cu113/torch_stable.html to solve this problem.

Actually, I recommend to use anaconda to install packages in normal cases because conda is very good at managing dependies of different packages. However, there are some packages must be installed using pip in this project. Sad, I have to say using pip troubles me a lot.
