Installation fails due to Pyperclip dependency

[mtomic123]

• PyTorch-Forecasting version: Latest
• PyTorch version: Latest
• Python version: 3.10.6
• Operating System: Linux on Google Cloud (No GUI)

Expected behavior

Install PyTorch-Forecasting on a linux machine without GUI.

Actual behavior

I wanted to train a PyTorch-Forecasting model on Google Cloud linux environment with a GPU. When I tried installing PyTorch-Forecasting with Poetry package manager, I got an error as package Pyperclip failed to install which is a dependency for PyTorch-Forecasting. The issue is that Pyperclip requires a GUI and obviously Google Cloud does not have one, its solely a terminal to which a user opens an SSH connection.

I installed all prerequisites for Pyperclip as outlined in their Github page.

Code to reproduce the problem

poetry add pytorch-forecasting (or pip install pytorch-forecasting).
