Use the files $CONDA_PREFIX/etc/conda/activate.d and $CONDA_PREFIX/etc/conda/deactivate.d, where $CONDA_PREFIX is the path to the environment. See the section on managing environments in the official documentation for reference.
A Common Problem: Suboptimal Channel Prioritization Anaconda distribution is designed and tested to use the anaconda channel (a subset of defaults) as its primary channel. Adding conda-forge in either a higher- (channel_priority: strict) or equal-priority (channel_priority: flexible) configuration opens up many of the packages to be sourced from Conda Forge instead, and this is where … Read more
Downgrading to conda 4.5.5 fixed this for me. And with a ranting hat on: This is the third time in the space of about 18 months that a conda update has resulted in an error that causes builds to fail, and there’s been plenty of other issues too. I presume it will be fixed by … Read more
As of conda 4.4, the command conda activate <envname> is the same on all platforms. The procedure to add conda to the PATH environment variable for non-Windows platforms (on Windows you should use the Anaconda Prompt), as well as the change in environment activation procedure, is detailed in the release notes for conda 4.4.0. For … Read more
You’ve answered your own question. In fact you really want to do conda install … instead of using pip if you can. You can install a conda package also without activating the environment. Just use conda install -n <env_name> <package> or conda install -p <path/to/env> <package>.
My original answer got flagged as duplicate because I answered a similar question with the same answer, I wasn’t aware that this is not allowed. I have marked my other response as a duplicate. Hopefully, this stays up! I almost spent two days running in circles trying all the solutions I could find on the … Read more
I had faced the same problem. Simply running conda install anaconda solved the problem for me.
The graphviz conda package is no Python package. It simply puts the graphviz files into your virtual env’s Library/ directory. Look e.g. for dot.exe in the Library/bin/ directory. To install the graphviz Python package, you can use pip: conda install pip and pip install graphviz. Always prefer conda packages if they are available over pip … Read more
Cause Changing Python versions without updating the conda package breaks Conda. . The Python version change (2.7.14 -> 3.6.8) created a situation where the new python has a new site-packages which no longer contains a conda package, whereas if you only update within 2.7.x, this wouldn’t be an issue. Conda includes both a set of … Read more
I don’t think the other answers are working any more, as conda stopped automatically setting environments up as jupyter kernels. You need to manually add kernels for each environment in the following way: source activate myenv python -m ipykernel install –user –name myenv –display-name “Python (myenv)” As documented here:http://ipython.readthedocs.io/en/stable/install/kernel_install.html#kernels-for-different-environments Also see this issue. Addendum: You … Read more
