You can install it directly from the environment pack version file:

pip install -r requirements.txt
or
conda env create -f torch_lts.yaml

Quick Configuration Environment

Method 1：

Create a virtual environment in Anaconda Powershell Prompt (Anaconda3) :

conda create -n torch_lts python=3.7

Then enter the virtual environment:

activate torch_lts

Finally, install the environment dependency package using the requirements. TXT file:

pip install -r requirements.txt

Method 2

Create virtual environments and install dependencies using conda and YAMl files directly from Anaconda Powershell Prompt (Anaconda3) :

conda env create -f torch_lts.yaml

Method 3

Execute the following commands directly in your environment to install:

conda install pytorch torchvision torchaudio cudatoolkit=11.1 -c pytorch-lts -c conda-forge

pip install numpy == 1.19.4
pip install pyecharts
pip install xlrd
pip install openpyxl
pip install matplotlib
pip install pandas

Import virtual environment in PyCharm:

When selecting the interpreter, do not create a new virtual environment and use the virtual environment you already created:

FAQ

If you run into a problem like RuntimeError: The size of tensor a (98) must match the size of tensor b (96) at non-singleton dimension 1, you can check torch version or modify code about Conv1d of TokenEmbedding in models/embed.py as the way of circular padding mode in Conv1d changed in different torch versions.
