Conda无法升级BLAS，该怎么办？

如何解决Conda无法升级BLAS，该怎么办？

我安装了openblas 1.0，在基本环境下运行conda update --all命令时，得到以下输出：

Collecting package metadata (current_repodata.json): done
Solving environment: \ 
The environment is inconsistent,please check the package plan carefully
The following packages are causing the inconsistency:

  - conda-forge/linux-64::opencv==4.5.0=py37_0
  - conda-forge/linux-64::openblas==0.3.11=pthreads_h04b7a96_1

## Package Plan ##

  environment location: /home/shared/conda3


The following packages will be UPDATED:

  blas                         pkgs/main::blas-1.0-openblas --> conda-forge::blas-2.2-openblas

The following packages will be DOWNGRADED:

  _openmp_mutex                                   4.5-1_gnu --> 4.5-1_llvm
  hdf5                           1.10.6-nompi_h1022a3e_1110 --> 1.10.6-nompi_h54c07f9_1110
  libgfortran-ng                          9.3.0-he4bcb1c_17 --> 7.5.0-hae1eefd_17
  libopenblas                    0.3.12-pthreads_h4812303_1 --> 0.3.12-pthreads_hb3c22a3_1
  scipy                                1.5.2-py37h14a347d_2 --> 1.5.2-py37h8911b10_2

但是在升级后版本仍然是1.0，因此此过程一次又一次地重复。我该怎么办才能避免这种情况？

我正在使用python 3.7.8和conda 4.9.1
