I know a similar question was asked before, but I’m getting a different error log and I haven’t been able to resolve the issue following the previous suggestions.

I suddenly started getting a similar error and I can’t run anything, even a streamlit hello.

Below is the message I get:

Traceback (most recent call last):

from google.protobuf.pyext import \_message  
ImportError: DLL load failed: The specified procedure could not be found.

Any suggestions what this may be? I was able to run streamlit with no issues a day or two ago, and as far as I can recall I haven’t made any changes to the code or installed packages.

Thanks

Hey @vbucaj 👋,

Thiago helped answer your question [on this thread](https://discuss.streamlit.io/t/importerror-dll-load-failed-the-specified-module-could-not-be-found/621/8). Just in case anyone else comes across this thread and has a similar issue, here is Thiago’s response from the other thread:

Based on this last line in your logs…

> File “c:\users\valmir\onedrive\covidtrends\venv\lib\site-packages\google\protobuf\descriptor.py”, line 47, in  
> from google.protobuf.pyext import \_message

…my guess is this is an issue with the `protobuf` package. Can you try reinstalling it?

But first, please let me know what version of the protobuf package you’re using in case we need to change Streamlit’s requirements to avoid that version 🙂 . For that, just open a Python console, and then:

```py
>>> import google.protobuf                 
>>> print("BAD VERSION: ", google.protobuf. __version__ )

```

Once you do that, please copy the output into this thread.

Then try installing the latest version:

```bash
pip uninstall protobuf
pip install protobuf

```

If that doesn’t work, try this instead:

```bash
pip install protobuf==3.11.2

```

If any of these work for you, please run this and post on this thread what it says:

```py
>>> import google.protobuf                 
>>> print("GOOD VERSION: ", google.protobuf. __version__ )
```
