Numpy error?

[seanmmorais]

Hi all, trying to run train.py for coseg_seg, but keep running into this error:

C:\Users\Smorais\Anaconda3\envs\meshcnn\lib\site-packages\torch\package_directory_reader.py:17: UserWarning: Failed to initialize NumPy: No module named 'numpy.core._multiarray_umath' (Triggered internally at ..\torch\csrc\utils\tensor_numpy.cpp:68.) _dtype_to_storage = {data_type(0).dtype: data_type for data_type in _storages} ------------ Options ------------- arch: meshunet batch_size: 12 beta1: 0.9 checkpoints_dir: ./checkpoints continue_train: False dataroot: datasets/coseg_aliens dataset_mode: segmentation epoch_count: 1 export_folder: fc_n: 100 flip_edges: 0 gpu_ids: [] init_gain: 0.02 init_type: normal is_train: True lr: 0.001 lr_decay_iters: 50 lr_policy: lambda max_dataset_size: inf name: coseg_aliens ncf: [32, 64, 128, 256] ninput_edges: 2280 niter: 100 niter_decay: 500 no_vis: False norm: batch num_aug: 20 num_groups: 16 num_threads: 3 phase: train pool_res: [1800, 1350, 600] print_freq: 10 resblocks: 3 run_test_freq: 1 save_epoch_freq: 1 save_latest_freq: 250 scale_verts: False seed: None serial_batches: False slide_verts: 0.2 verbose_plot: False which_epoch: latest -------------- End ---------------- computing mean std from train data...

This is my command: python train.py --dataroot datasets/coseg_aliens --name coseg_aliens --arch meshunet --dataset_mode segmentation --ncf 32 64 128 256 --ninput_edges 2280 --pool_res 1800 1350 600 --resblocks 3 --lr 0.001 --batch_size 12 --num_aug 20 --slide_verts 0.2

Anyone have any idea what's going on? I've tried different versions of numpy (1.15.0, 1.19) and get the same error.

I guess that's a problem with the version update. Have you tried downgrading the numpy? pip install numpy==1.21.6

My Python version is 3.6.8, I reinstalled numpy 1.19.2 and it worked!
