There is a question about installing smiles-featurizers

Building wheels for collected packages: cryptacular
Building wheel for cryptacular (pyproject.toml) ... done
WARNING: Building wheel for cryptacular failed: [Errno 2] No such file or directory: 'C:\Users\Tian\AppData\Local\Temp\pip-wheel-w0skx4fb\cryptacular-1.6.2-cp38-cp38-win_amd64.whl'
Failed to build cryptacular
ERROR: Could not build wheels for cryptacular, which is required to install pyproject.toml-based projects.

So how to fix it?

Hi @Tian1225, Maybe the following Stackoverflow thread could be useful here:

Please let me know if this resolves the issue for you.

Thanks for your answer！But,there is a new problem in use.

TypeError: Descriptors cannot not be created directly.
If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:

1. Downgrade the protobuf package to 3.20.x or lower.
2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

I have update the protoc and downgrade the protobuf package, the TypeError still exitence.

You were only required to only downgrade the version of protobuf that might have been enough.

Additionally, if the local environment still does not work for you can also try smiles-featurizes on a colab notebook here.

I have fixed the problem. Thank you!

@Tian1225 Could you please state your solution for future users?

When using pip in anaconda to install smiles-featurizers in a virtual environment, the following error occurs:

TypeError: Descriptors cannot not be created directly.

When using pip in anaconda to install smiles-featurizers in a virtual environment, the following error occurs:
First you need to uninstall protobuf (pip uninstall protobuf)
Then install protobuf==3.19.0 (pip install protobuf==3.19.0)
If there is an error about the channel in the above method, you can use conda to install protobuf==3.19.0 (conda install protobuf==3.19.0)
Hope this helps future users who encounter such problems.
