Streamlit Not Working for Librosa

☁️ Community Cloud
, ,
1

I have built a model to take an audio file and classify its emotion. The model works perfectly in Google Colab and now I am working to make it available through Streamlit. Following are the libraries I use and I have verified the versions in my program. I have added these on the requirements.txt file.

scikit-learn==1.2.2
numpy==1.21.0
pandas==1.5.3
joblib==1.3.2
librosa==0.10.0.post2
xgboost==1.7.6

Based on the previous discussion on this page, I have also added another file packages.txt with the following code: libsndfile1-dev

Below is the error I am getting. Please help with this.

Hi @Chirag_Saraogi, and welcome to our community! :wave:

You may need to install the libsndfile1 package (not Dev) in your packages.txt file.

If that doesn’t fix the issue, could you please provide us with the full error log trace?

Thanks,
Charly

Hi @Charly_Wargnier ,

thank you so much for helping me with this. I did change the code in the packages.txt file but it still gave the same error. Below is the error log. Please let me know if I can provide any more information about the project to help resolve this. Thank you.

Can you provide the log trace in a text format please?

Thanks,

Thanks, @Chirag_Saraogi!

The error message indicates that Numba needs NumPy 1.24 or a lesser version

Can you try downgrading, e.g.:

pip install numpy==1.24

Thanks.

@Charly_Wargnier

I am using the following code in the requirements file.

numpy==1.21.0

Should I install NumPy in the packages.txt code? I tried different versions and many ways to resolve the issue but could not find any way to resolve it. Please help with this.

Thank you

8

@Charly_Wargnier

I am sorry, I am using the versions below

scikit-learn==1.2.2
numpy==1.23.5
pandas==1.5.3
joblib==1.3.2
librosa==0.10.0.post2
xgboost==1.7.6

Add streamlit to your requirements.txt.

10

Hi Goyo,

Thank you for your reply. I have added these libraries and their versions to the requirements.txt file already. But I am still not able to resolve the error.

Thank you

Please share the link to your public github repo.

Thank you for helping me with this. Below is the link to my GitHub Repository for the project.

Hi @Charly_Wargnier

I have already downgraded the NumPy version. Please help me resolve this. Below is the link to my github repository.

Thank you

Hi @Franky1

Please help me resolve the issue with the Streamlit. I really want to continue using Streamlit for my projects.

Thank you

15

I cannot find streamlit in your requirements.txt.

16

Hi @Goyo

Based on what I understood, Streamlit was already installed and I am not able to resolve the issue by adding streamlit.

Thank you

17

If you don’t add streamlit to your requirements file, it is automatically installed at the end. This sometimes can trigger the installation of different versions of the same packages you are requesting. So you can end up with numpy==1.25.2 even if you requested a lower version. You can see it happening in the logs.

18

I fixed some bugs, see my fork and pull request:

App seems to work, however, there are still some warnings in the console…
