Ubuntu CommandNotFoundError: Your shell has not been properly configured to use ‘conda activate‘.

报错

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If your shell is Bash or a Bourne variant, enable conda for the current user with

    $ echo ". /home/wl/anaconda3/etc/profile.d/conda.sh" >> ~/.bashrc

or, for all users, enable conda with

    $ sudo ln -s /home/wl/anaconda3/etc/profile.d/conda.sh /etc/profile.d/conda.sh

The options above will permanently enable the 'conda' command, but they do NOT
put conda's base (root) environment on PATH.  To do so, run

    $ conda activate

in your terminal, or to put the base environment on PATH permanently, run

    $ echo "conda activate" >> ~/.bashrc

Previous to conda 4.4, the recommended way to activate conda was to modify PATH in
your ~/.bashrc file.  You should manually remove the line that looks like

    export PATH="/home/wl/anaconda3/bin:$PATH"

^^^ The above line should NO LONGER be in your ~/.bashrc file! ^^^

运行提示里给出的前面两个解决办法，不能解决问题。按照后面的提示，修改.bashrc后，可以解决问题，但是在后面安装pytorch后在conda list中可以找到pytorch，却无法在Python环境下import torch。

查到另外的解决办法，一行代码即可解决：

source activate

之后再运行conda activate就没有问题了！

可能是因为之前没有**？咱也不知道，咱也不敢问……苏大强脸.jpg
