无法在Ubuntu 16.04中的anaconda中安装cv2

Question

当我尝试使用以下方法安装tensorflow时：

conda install -c conda-forge opencv 

我遇到以下错误

Traceback (most recent call last):
    File "/home/pawan/anaconda3/lib/python3.6/site-packages/anaconda_navigator/api/anaconda_api.py", line 496, in _conda_info_processed
    /processed_info = self._process_conda_info(info)
  File "/home/pawan/anaconda3/lib/python3.6/site-packages/anaconda_navigator/api/anaconda_api.py", line 607, in _process_conda_info
    processed_info = info.copy()
    AttributeError: 'bytes' object has no attribute 'copy'

我先卸载然后重新安装了anaconda，但最后还是遇到了相同的错误
