conda environment compile tutorial！

[xyb1314]

So start from below command to download some neccessary libs and package on conda env.

apt-get install libgl1 libglib2.0-0 libsm6 libxrender1 libxext6 libssl-dev build-essential g++ libboost-all-dev libsparsehash-dev git-core perl libegl1-mesa-dev libgl1-mesa-dev -y
conda create -n texgen python=3.10 -y
conda activate texgen
conda install ninja -y
conda install -c "nvidia/label/cuda-11.8.0" cuda-toolkit -y
conda install pytorch==2.1.0 torchvision==0.16.0 pytorch-cuda=11.8 -c pytorch -c nvidia -y
conda install h5py pyyaml -c anaconda -y
conda install sharedarray tensorboard tensorboardx yapf addict einops scipy plyfile termcolor timm gxx=11.1.0 lightning -c conda-forge -y
conda install pytorch-cluster pytorch-scatter pytorch-sparse -c pyg -y
pip install -r requirements.txt

when you run this command pip install -r requirements.txt , this is error( on my server ) on below:

Usage: pip [options]
ERROR: Invalid requirement: flash-attn --no-build-isolation
pip: error: no such option: --no-build-isolation

comment the flash-attn --no-build-isolation in requirements.txt , and continue running pip install -r requirements.txt.
error occurs:

ERROR: Could not find a version that satisfies the requirement xformers==0.0.22.post7+cu118 (from versions: 0.0.1, 0.0.2, 0.0.3, 0.0.4, 0.0.5, 0.0.6, 0.0.7, 0.0.8, 0.0.9, 0.0.10, 0.0.11, 0.0.12, 0.0.13, 0.0.16rc424, 0.0.16rc425, 0.0.16, 0.0.17rc481, 0.0.17rc482, 0.0.17, 0.0.18, 0.0.19, 0.0.20, 0.0.21, 0.0.22, 0.0.22.post7, 0.0.23, 0.0.23.post1, 0.0.24, 0.0.25, 0.0.25.post1, 0.0.26.post1, 0.0.27, 0.0.27.post1, 0.0.27.post2, 0.0.28, 0.0.28.post1, 0.0.28.post2, 0.0.28.post3, 0.0.29, 0.0.29.post1, 0.0.29.post2, 0.0.29.post3, 0.0.30.dev989, 0.0.30.dev1002)

ERROR: No matching distribution found for xformers==0.0.22.post7+cu118

if you have problems to connect the link to download xformer, you can comment it in requirements.txt and download it(0.0.22.post7+cu118_cp310) via https://download.pytorch.org/whl/xformers/. and pip instll xformer_xxx.whl offline.

after installing xformer ,rerun the pip install -r requirements.txt , and take much time on torchsparse installation.

Collecting git+https://github.com/mit-han-lab/torchsparse.git (from -r requirements.txt (line 24))

and error occurs when git clone the https://github.com/mit-han-lab/torchsparse.git and python setup.py install :

torchsparse/torchsparse/backend/others/query_cpu.cpp:6:10: fatal error: google/dense_hash_map: No such file or directory
6 | #include <google/dense_hash_map>
| ^~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
ninja: build stopped: subcommand failed.

solution is https://github.com/facebookresearch/SparseConvNet/issues/96 , the detailed step :
conda install google-sparsehash -c bioconda and add the path export PATH=/path/to/anaconda3/envs/yourenv/include:$PATH

solved it and install other required package and module in requirments.txt

download whl flash_attn and pip install whl offline , saving time for compile like pip install flash_attn --no-build-isolation and easier!

and downgrade huggingface-hub to 0.25.2, it can download the model from huggingface straightly ! (if available to huggingface.com)
