I have been using pennylane for quantum circuit building, but while compiling I am getting the following error:

```auto
Traceback (most recent call last):
  File "/home/shuhul.handoo/shuhul/code/train.py", line 2, in <module>
    from models import build_generator, build_discriminator

    from semantic_version import SimpleSpec, Version
ImportError: cannot import name 'SimpleSpec' from 'semantic_version' (/home/shuhul.handoo/anaconda3/lib/python3.9/site-packages/semantic_version/ __init__.py)

```

First I thought this was error with installing Pennylane using `pip` but after installing pennylane using the command `conda install -c conda-forge pennylane` I still get this error. What should be done?

Hi @shuhul, welcome to the forum!

I do think this is an installation issue. Please try creating a new environment following the step-by-step below:

Create a new conda environment with:  
`conda create --name name_of_your_environment python=3.9`  
Activate the environment:  
`conda activate name_of_your_environment`  
After this you can install the needed packages:  
`python -m pip install pennylane`

Please let me know if this works for you!
