I cant seem to figure out the code on how i can use the data received from Pandas DF to create a new file in Power BI and plot a graph using the data in a external IDE.The graph has to be in power BI hence the issue i am currently facing.
so i am wondering if it is possible to create a power bi file and plot the graph using only code from an external python IDE.(Not too versed in using power bi so there might be many solutions i might not know about)
Any suggestions would also be greatly appreciated.

I have got a training dataset of 1,000 images but while compiling my code, I came across this error;
Error: ValueError: Empty training data?
What's the possible solution? Thanks
The issue is that there is no validation or test dataset in your directory. Ensure you have data in your validation directory.

Having a df of data, doing:
fig=px.line(df, x='date', y='px', color='description')
The following graph is rendered like the image attached. Is this an expected behavior? How do I make dots connect only in a time-ordered fashion?
Yes, this is observed in plotly plots.
The data is required to be sorted before the plotting.

I'm trying to use pyzbar to read multiple barcode, however it seems like I can't read multiple instead of only one big bounding boxes.
When you call pyzbar.decode it will decode all 1D barcodes in your image. For example:
from pyzbar.pyzbar import decode
from PIL import Image
for bar in decode(Image.open('benchmark.jpg')):
print(bar.data)
will print out
b'12345678'
b'12345678'
b'0000123456784'
However in your case all barcodes are identical so pyzbar just returns a list with a single element. It would work if they were different however.

First read this :
http://docs.python.org/2/library/stdtypes.html#bltin-file-objects
then write some code and come back with concrete questions if necessary.
