Numpy Version?

[Hiusam]

Does pytorch3d only support numpy and numpy-base with version >= 1.21?
I have a package compatible with numpy <= 1.19.5 only what can I do?

[bottler]

No, we shouldn't have a requirement for such a new numpy. Why would you think we might?

[Hiusam]

Because when I execute:
conda install pytorch3d -c pytorch3d
conda says:

==> WARNING: A newer version of conda exists. <==
  current version: 4.10.3
  latest version: 4.11.0

Please update conda by running

    $ conda update -n base -c defaults conda



## Package Plan ##

  environment location: /home/xurunsen/anaconda3/envs/pytorch3d

  added / updated specs:
    - pytorch3d


The following NEW packages will be INSTALLED:

  mkl_fft            pkgs/main/linux-64::mkl_fft-1.3.1-py37hd3c417c_0
  mkl_random         pkgs/main/linux-64::mkl_random-1.2.2-py37h51133e4_0
  numpy              pkgs/main/linux-64::numpy-1.21.2-py37h20f2e39_0
  numpy-base         pkgs/main/linux-64::numpy-base-1.21.2-py37h79a1101_0
  pytorch3d          pytorch3d/linux-64::pytorch3d-0.6.1-py37_cu102_pyt190

It tries to install such a new version.

[Hiusam]

I think mayne such a new version numpy is required by pytorch1.9(cuda 10.2).

[bottler]

This is odd. It thinks you don't have numpy (because it says INSTALLED not UPGRADED). Can you paste the full output of conda list before you run that command?

[Hiusam]

Because I uninstalled the numpy at that time.
Here is my original env without installing pytorch3d and its requirements.

I think the problem is that my original environment is installed with NumPy 1.19.5 and when installing pytorch3d, it tries to install NumPy-base 1.21.2, and my env cannot work properly.
I have solved the problem by installing PyTorch and pytorch3d first, which will install NumPy 1.21.2 and then installed other packages that required lower version NumPy, and NumPy will become 1.195. It seems that the env works well in this way, though I think there may be some inconsistency.

I think the distinction might be whether numpy is installed from conda or not. The PyTorch3D conda package depends on the numpy conda package, and your numpy was from pypi. So when you try to install pytorch3d it is as if you don't have numpy so tries to find it, which takes the current version. I'm glad you've got round the problem.
