How to interpret conda package conflicts?

Some Practical Advice @Quantum7’s answer gives a fine literal interpretation of Conda’s conflict reporting. However, I wanted to offer a more practical take, which is that this “feature” from Conda is too non-specific to be useful in most non-trivial environments. And sometimes it won’t even include the underlying conflict. Don’t waste your time with it! … Read more

Why are packages installed rather than just linked to a specific environment?

Conda already does this. However, because it leverages hardlinks, it is easy to overestimate the space really being used, especially if one only looks at the size of a single env at a time. To illustrate the case, let’s use du to inspect the real disk usage. First, if I count each environment directory individually, … Read more

How to activate an Anaconda environment

If this happens you would need to set the PATH for your environment (so that it gets the right Python from the environment and Scripts\ on Windows).

What is the difference between pip and conda?

Quoting from the Conda blog: Having been involved in the python world for so long, we are all aware of pip, easy_install, and virtualenv, but these tools did not meet all of our specific requirements. The main problem is that they are focused around Python, neglecting non-Python library dependencies, such as HDF5, MKL, LLVM, etc., … Read more

Conda environments not showing up in Jupyter Notebook

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.
