Summary

PLS HELP TO RESTORE TO LAST WORKING ENV.

Everything was working fine for months , I accidentally upgraded streamlit 1.18.1 using –

$ conda install -c conda-forge streamlit

which i noticed downgraded my streamlit to 1.8.0!
then i remember should’ve used pip

used following to restore conda env (from revision 8 latest to previous 7)

$ conda install --revision 7

seemed to work correctly .

But since conda’s streamlit seemed to have removed streamlit 1.18 had to reinstall streamlit with pip using-

$pip install --upgrade streamlit

seeemd to work fine but now streamlit throwing errors -

$ streamlit hello

Hi @Free-Radical

I’m not an expert on conda, but the error seems to indicate an issue importing Google’s protobuf package. If you’ve installed Streamlit in the conda environment with pip, could you in the same env try installing protobuf?

$ pip install protobuf
$ streamlit hello

or

$ pip install -U protobuf
$ streamlit hello

Let me know if either of those helped

$ pip install -U protobuf

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If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc 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).
