  3. First we will install Jupyter notebook, which is an essential tool for interactive data analysis and experimentation. It will also tell you about other packages that will be automatically updated or changed with the update. The list will include versions of each package, the specific build, and the channel that the package was downloaded from.
  4. I'm not really sure how to debug so any advice would be greatly appreciated. Using conda, you can create an isolated python environment for your project. It is always better to use different environment for different purpose and install necessary package in a particular environment, so that each environment is orthogonal and does not interfere with each other.
  5. There might be dependencies elsewhere that I could also get rid of. This is what the installer looks like- For a detailed guide on how to set up Python for your machine, read up on. This platform is the one where this spec file is known to work. To ensure that the packages work correctly, make sure that the file was created from a working environment, and use it on the same architecture, operating system and platform, such as linux-64 or osx-64. In fact, conda hangs in a similar way after pressing Ctrl-C while installing anything. I decided to install miniconda, so I go to for downloading miniconda. You can name these scripts anything you like. In my experience, Conda does an excellent job managing dependencies and installing new packages, allowing you to install the packages you want and get back to work… eventually. By doing this, the resulting environment file is very detailed with specific version listing. Anaconda has all the necessary packages, while miniconda will have only the basic thing installed, so that we can install everything later.
  6. OpenCV(cv2)をcondaでインストール (python3.6) - Have a question about this project?
  7. Review from Preliminary What is Conda. It is a data science platform that comes with a lot of packages. Run the command below to use conda within miniconda. conda solving environment For this tutorial, I am using Anaconda. If you have miniconda, the commands will be the same. This also applies across operating systems Except for the activation of environment. It will also tell you about other packages that will be automatically updated conda solving environment changed with the update. If there are newer version available, follow the instruction to install the newest version of conda. In my case, the conda needed to be updated, along with this update, some dependencies also need to be updated. Managing Environments What is a conda environment and why is conda solving environment so useful. Using conda, you can create an isolated python environment for your project. An environment is a set of packages that can be used in one or multiple projects. The default environment with Anaconda is the root environment, which contains Anaconda default packages listed. There are two ways of creating a conda environment. Creating environment with an environment file. An example of environment file environment. Conda is friendly with pip, so if some packages are not found in Anaconda Cloud, then you can install them with pip install. Open up your favorite text editor, copy and paste the code below, save your file as environment. Note: This command is slighty different between operating systems. This is also a great way to see the list of environments that have been created. In the list, the path to each environment is also shown. Sharing Environments with others To share an environment, you can export your conda environment to an environment file. By doing this, the resulting environment file is very detailed with specific version listing. Exporting your environment to a file called myenv. Note that this environment file will not work to share across platforms, since the conda solving environment and versions might be different for different operating systems. Conda solving environment will ensure you have the most up to date version that will work across platform. If you follow these guidelines, you should be able to give your environment file to anyone, and they will be able to install your packages with no problem. Making an exact copy of an environment and deleting environments Copying an environment We can make an exact copy of an environment to an environment with a different name. This maybe useful for any testing versus live environments or python 2. Managing Packages Seeing what packages are available We will now check packages that are available to us. The list will include versions of each package, the specific build, and the channel that the package was downloaded from. Searching for a certain package Some packages might not be available in conda, but are available in. For example, we will search for rasterio within the. Each channels contains one or more conda packages. It is important to be careful when downloading any packages from an untrusted source. It is wise to research about the source of a conda package. In this example, we will use rasterio from conda-forge. The first word list the channel that this package is from and the second part shows the name of the package. To install the latest version available within the channel, do not specify in the install command. We will install version 0. Conda will also automatically install the dependencies for this package.
