Python Installation on Ubuntu¶

Python is only needed if you need to use Python and the PySpark engine in Fire Insights. Python modules in Fire Insights use Python 3.7+.

Check if Python 3.7+ is Installed¶

Use the below commands:

python --version
python3.7 --version

Install Python 3.7 (if not installed)¶

Some References for Installing Python:

Ubuntu : https://linuxize.com/post/how-to-install-python-3-7-on-ubuntu-18-04/

Prerequisites¶

update the packages list and install the packages necessary to build Python source:

sudo apt update

Install needed dependency:

sudo apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev wget libbz2-dev``

Download and extract the downloaded package¶

Download python from below Link

https://www.python.org/downloads/

https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz

Download and untar:

wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
tar xzf Python-3.7.0.tgz

Next, navigate to the Python source directory and run the configure script which will perform a number of checks to make sure all of the dependencies on your system are present:

cd Python-3.7.0

Build & compile:
```
./configure --enable-optimizations
```

Install the Python binaries by running the following command:
```
make altinstall
```

Note: Do not use the standard make install as it will overwrite the default system python3 binary.

Verify it by typing:

python3.7 –-version

Create Python virtual environment & Activate it¶

Create Python virtual environment & Activate it:

python3.7 -m venv venv
source venv/bin/activate
python --version

Upgrade pip version¶

Upgrade pip version with 20.0 or above:

pip install pip --upgrade

pystan dependency:
```
pip install pystan
```

pip install convertdate
```

fbprophet dependency:
```
pip install fbprophet
```

Check pip list:
```
pip list
```

Install Other Packages¶

Install the required packages:

cd fire-x.y.x/dist/fire
pip install -r requirements.txt

requirements.txt file is available in the installation directory of fire insights:

fire-x.y.x/dist/fire/requirements.txt

Delete a venv¶

To delete a virtual environment, follow below steps:

source venv/bin/activate
pip freeze > requirements.txt
pip uninstall -r requirements.txt -y
deactivate
rm -r venv/
