How to download a file on jupyter notebook

If you want to know what is actually executed when you type python , you can use the type shell command:. You can optionally add the -a tag to see all available versions of the command in your current shell environment; for example:. Python uses a similar mechanism to locate imported packages. The list of paths searched by Python on import is found in sys.

By default, the first place Python looks for a module is an empty path, meaning the current working directory. If the module is not found there, it goes down the list of locations until the module is found.

In most cases, a Python package you install with pip or with conda will be put in a directory called site-packages. The important thing to realize is that each Python executable has its own site-packages : what this means is that when you install a package, it is associated with particular python executable and by default can only be used with that Python installation! We can see this by printing the sys. The full details here are not particularly important, but it is important to emphasize that each Python executable has its own distinct paths , and unless you modify sys.

When you run pip install or conda install , these commands are associated with a particular Python version:. So, for example we see that pip install will install to the conda environment named python3. And conda install will do the same, because python3. The reason both pip and conda default to the conda python3. I'll say this again for emphasis: the shell environment in Jupyter notebook matches the Python version used to launch the notebook. The next relevant question is how Jupyter chooses to execute Python code, and this brings us to the concept of a Jupyter Kernel.

A Jupyter kernel is a set of files that point Jupyter to some means of executing code within the notebook. To see the kernels you have available on your system, you can run the following command in the shell:. Each of these listed kernels is a directory that contains a file called kernel. For example:. If you'd like to create a new kernel, you can do so using the jupyter ipykernel command ; for example, I created the above kernels for my primary conda environments using the following as a template:.

Now we have the full background to answer our question: Why don't! The root of the issue is this: the shell environment is determined when the Jupyter notebook is launched, while the Python executable is determined by the kernel, and the two do not necessarily match. In my current notebook environment, the two differ. This is why a simple! As noted above, we can get around this by explicitly identifying where we want packages to be installed. Remember: you need your installation command to match the current python kernel if you want installed packages to be available in the notebook.

So, in summary, the reason that installation of packages in the Jupyter notebook is fraught with difficulty is fundamentally that Jupyter's shell environment and Python kernel are mismatched , and that means that you have to do more than simply pip install or conda install to make things work. The exception is the special case where you run jupyter notebook from the same Python environment to which your kernel points; in that case the simple installation approach should work. But that leaves us in an undesireable place, as it increases the learning curve for novice users who may want to do something they rightly presume should be simple: install a package and then use it.

So what can we as a community do to smooth-out this issue? As I mentioned, the fundamental issue is a mismatch between Jupyter's shell environment and compute kernel. So, could we massage kernel specifications such that they force the two to match?

Perhaps: for example, this github issue shows an approach to modifying shell variables as part of kernel startup. Basically, in your kernel directory, you can add a script kernel-startup. Then in your kernel. A similar approach could work for virtualenvs or other Python environments. There is one tricky issue here: this approach will fail if your myenv environment does not have the ipykernel package installed, and probably also requires it to have a jupyter version compatible with that used to launch the notebook.

So it's not a full solution to the problem by any means, but if Python kernels could be designed to do this sort of shell initialization by default, it would be far less confusing to users:! In this case pip install will install packages to a path inaccessible to the python executable. For this reason, it is safer to use python -m pip install , which explicitly specifies the desired Python version explicit is better than implicit , after all.

This is one reason that pip install no longer appears in Python's docs , and experienced Python educators like David Beazley never teach bare pip.

CPython developer Nick Coghlan has even indicated that the pip executable may someday be deprecated in favor of python -m pip.

Even though it's more verbose, I think forcing users to be explicit would be a useful change, particularly as the use of virtualenvs and conda envs becomes more common. For symmetry with pip , it would be nice if python -m conda install could be expected to work in the same way the pip counterpart does. You can call conda this way in the root environment, but the conda Python package as opposed to the conda executable cannot currently be installed anywhere but the root environment:.

I suspect that allowing python -m conda install in all conda environments would require a fairly significant redesign of conda's installation model, so it may not be worth the change just for symmetry with pip 's API. That said, such a symmetry would certainly be a help to users. Another useful change conda could make would be to add a channel that essentially mirrors the Python Package Index , so that when you do conda install some-package it will automatically draw from packages available to pip as well.
