Conda is an open-source package and requirements.txt file.
requirements.txt file?Why do we need to share the environment? For that, let's take a look at a possible real-world scenario. Consider that we are working on a project along with our team. Our task is to build the back end of the web application using Python's Django framework. We use Conda as our package and environment manager to create an environment in which we install Python 3.10.1 and Django 4.2.3. After a month of hard work and testing, we have finally completed the back end and pushed the code on GitHub. Our team pulls the code in their local systems and tries to run it, but the code does not work on their local systems.
The reason was that the Python and Django versions the team installed on their systems were not the same as the version in which we were writing the code, and thus dependencies issues emerged.
In this case, we need to share the exact packages and dependencies we used in our system with our team. In this Answer, we will explore how we can create the requirements.txt file to store the dependencies and install them.
requirements.txt fileNote: Before creating the requirements.txt file, we need to ensure we have activated our Conda environment.
To store all of the packages and dependencies installed in our environment, we can run the following command.
conda list -e > requirements.txt
After running this command, the requirements.txt file will be created in the directory we are currently in. The structure of the requirements.txt file is given below.
technology1 == versiontechnology2 == versiontechnology3 == versiontechnology4 == version...
For the scenario discussed above, running the command will create a requirements.txt file with the following dependencies.
Django == 4.2.3python == 3.10.1
requirements.txt fileOnce the requirements.txt file is created, we can share it with our team or another environment and install the dependencies. For that, we can run the following command.
conda install --file requirements.txt
On running the command, the dependencies will install in the system, and we are ready for coding.
Creating the requirements.txt file is important for code collaboration and sharing among different systems and environments.
