Not able to run import polars as pl inside kernprof
Chuck321123 opened this issue · 1 comments
So if you toss in import polars as pl inside a code you will get an error that it cannot import lazyframe from polars. However, i am able to import perfectly fine in normal python. The command i use to run in anacoda promt after specifying path: kernprof -l "Line Profiler.py".
My code:
from line_profiler import LineProfiler
@profile
def my_function():
print("running")
import pandas as pd
import numpy as np
import polars as pl
my_function()
Error message: ImportError: cannot import name 'LazyFrame' from 'polars.lazyframe.frame'
polars version=0.20.21
python=3.12.2
line_profiler=4.1.2
OS: Win-11
Works fine for me on Ubuntu with Python 3.11.2 and Python 3.12.3 (using pyenv not conda).
Also FYI, as of version 4.0 you can write your code like:
from line_profiler import profile
@profile
def my_function():
print("running")
import pandas as pd
import numpy as np
import polars as pl
my_function()
And the previous invocation kernprof
works, but you can also set the environment variable LINE_PROFILE
and run as normal:
LINE_PROFILE=1 python "Line Profiler.py"
