Error "FileNotFoundError" while the file exists

🎈 Using Streamlit
1

Hello,

I’m trying to deploy my first streamlit app to present a datascience project.
i’m new in using it.
My streamlit app works fine when I run it on the local way.

The problem is for the “Exploration des donnĂ©es” section.
Normally, some random image have to appears among the category selected.

But in the error message, it seems that streamlit is looking for an image name like “image_imageid.0_product_productid.0.webp” but the right image file name is like image_imageid._product_productid.webp".

image
image1005×58 2.88 KB

the image “image_1263597046_product_1263597046.webp” exist in the “img_train” librairy.
Working on it for days and can’t understand why this “0” appears.

The problem seems to come from this line code. But I use it for others thing in the app and it works.

filename = f"img_train/image_{row.imageid}_product_{row.imageid}.webp"
                image = Image.open(filename)

Here my code

global code to select ramdom image according the category of images

tabs = st.tabs(list(categories.prdlabelcode.array))

    nb_sample = 3
    for i in range(0, len(categories)):
        with tabs[i]:
            st.markdown(f"<p><strong>Exemples d'annonces de la catégorie {categories.iloc[i].prdlabelcode}</strong></p>", unsafe_allow_html=True)
            category = categories.iloc[i].prdtypecode
            sample = X[y_train.prdtypecode == category].sample(nb_sample)
            cols = st.columns([1]*nb_sample)
            index=0
            for indice, row in sample.iterrows():
            
                filename = f"img_train/image_{row.imageid}_product_{row.imageid}.webp"
                image = Image.open(filename)
                cols[index].image(image, use_column_width=True)
                cols[index].write(f'<p class="titre_annonce">{row.designation[:50]}</p>', unsafe_allow_html=True)
                if str(row.description) != "nan":
                    cols[index].write(row.description[:300])
                index += 1
            category_image = f'categories-{"{:02d}".format(i)}n.webp'
            st.markdown("<p><strong>Nuage de mot et fréquence des mots de la catégorie</strong></p>", unsafe_allow_html=True)    
            st.write("""Pour avoir une idée plus précise du contenu du texte des annonces par catégorie, **nous avons réalisé des nuages de mots et des histogrammes avec les mots les plus fréquents par catégorie.**
            """)
            st.image(category_image)

Thank you.

Because row.imageid is a float and that is how floats are converted to string by default.

>>> f"{float(1263597046)}"
'1263597046.0'

You can simply replace {row.imageid} with {int(row.imageid)}
