FastF1 is a python package for accessing and analyzing Formula 1 results, schedules, timing data and telemetry

fast-f1's Issues

Installed but not really able to do anything

Hello,

sorry for being a complete beginner to programming. But I'm not able to really do anything. just tried the example provided:

"import fastf1 as ff1
from fastf1 import plotting
from matplotlib import pyplot as plt
plotting.setup_mpl()
ff1.Cache.enable_cache('path/to/folder/for/cache') # optional but recommended
race = ff1.get_session(2020, 'Turkish Grand Prix', 'R')
laps = race.load_laps()
lec = laps.pick_driver('LEC')
ham = laps.pick_driver('HAM')"

So I'm getting an error code of:

"File "C:****\F1\F1FastTest.py", line 12, in plotting.setup_mpl()
AttributeError: module 'fastf1.plotting' has no attribute 'setup_mpl'"

and if I comment it out it gets stuck at:

"File "C:**\anaconda3\envs\spyder\lib\site-packages\requests_cache\backends\storage\dbdict.py", line 74, in connection
con = sqlite.connect(self.filename)
OperationalError: unable to open database file"

I tried several Python versions but didn't seem to fix the issue. Is it because ther eis a live session going on? Or am I just too stupid to operate this :)

Check Tyre Compound

How can we check the tyre compound and age when returning data of fastest lap of each driver?

Unable to get telemetry data from quali and race of Bahrain GP. (Worked well in Free practice sessions)

The library worked well in FP1, FP2 and FP3 recording sessions and than analyzing them. In Quali and race I got this error, but the code and the method I used are the same!! So strange. I updated to 2.1.4 today but I still have the same problem...

Questions and Answers about Imola friday

For 3 times every 3 minutes, when I am recording fp1 data, cmd tells me 'received no data for more than 60 seconds, exiting'. I don't know, my connection seems stable, but maybe this is the problem and I am wrong... Anyway the file it saved is not txt but it's a file that windows doesn't recognize. Is it normal? And HOW to downgrade to 2.1.4 if I get the same problem in FP2????

UnboundLocalError: local variable 'df' referenced before assignment

For FP1 of the 2021 Emilia Romagna Grand Prix the load_laps function in core.py errors out with a UnboundLocalError on line 1192.

Fast-F1/fastf1/core.py

Line 1192 in 8da6cbb

laps = df.reset_index(drop=True) # noqa: F821

I've traced it back to the fact that no drivers are getting any data back from the timing_app_data api call. The useful data frame is empty, so when the for each driver loop occurs the length of d2 is always 0, meaning the loop ends without df ever having being initialized as a variable.

Fast-F1/fastf1/core.py

Lines 1168 to 1190 in 8da6cbb

	for i, driver in enumerate(self.drivers):
	d1 = data[data['Driver'] == driver]
	d2 = useful[useful['Driver'] == driver]
	if len(d2) == 0:
	continue # no data for this driver; skip
	result = pd.merge_asof(d1, d2, on='Time', by='Driver')
	# calculate lap start time by setting it to the 'Time' of the previous lap
	laps_start_time = list(result['Time'])[:-1]
	if self.name == 'Race':
	# assumption that the first lap started when the session was started can only be made for the race
	laps_start_time.insert(0, self.session_start_time)
	else:
	laps_start_time.insert(0, pd.NaT)
	result.loc[:, 'LapStartTime'] = pd.Series(laps_start_time, dtype='timedelta64[ns]')
	for npit in result['NumberOfPitStops'].unique():
	sel = result['NumberOfPitStops'] == npit
	result.loc[sel, 'TotalLaps'] += np.arange(0, sel.sum()) + 1
	# check if df is defined already before concat (vars is a builtin function)
	df = result if 'df' not in vars() else pd.concat([df, result], sort=False) # noqa: F821

Qualifying data unavailable during sprint race weekend

Hello,

I'm trying to load the data for todays qualifying and the Ergast API lookup fails (obviously not fastf1's fault).
How will getting data for this qualifying and the sprint race qualifying work if Ergast doesn't update their API?

Thank you.

Availability of the Ax6's V1.5.11

Hi,
I've the ZIP file downloaded by Ax6 github before it disappeared.
It should be v.1.5.11 with some modification made after this year winter testing.
It seems to be better commented and have some differences with your code.

StatusSeries error

So I downloaded the live data from qualifying yesterday and trying to load it into python I'm getting this error. Is it really supposed to download api data when I have the live-data downloaded? Or is it for meta data?

Issue with loading data for the correct race

Microsector analysis

Hi, with Fast-F1 is it possible to create an analysis of the Microsectors? Let me explain better, a map of the circuit where the driver who made the best micro-sector is highlighted, for example in Q3. I don't know if I've made myself clear

Inconsistent Alpine Name

Only a minor issue, but the driver data in the API uses "Alpine F1 Team", the docs for plotting.TEAM_COLORS and plotting.TEAM_TRANSLATE say "Alpine F1 Team", but for me in 2.1.6 those actual dictionaries use "Alpine".

Wrong LapTime Y Axis

plotting.laptime_axis(ax)

this function misses the lapTime.

utils.delta_time function returns KeyError

import fastf1 as ff1
from fastf1 import plotting
from matplotlib import pyplot as plt
from fastf1 import utils

plotting.setup_mpl()
quali = ff1.get_session(2021, 'Bahrain', 'Q')
laps = quali.load_laps()
lec = laps.pick_driver('LEC').pick_fastest()
ham = laps.pick_driver('HAM').pick_fastest()

delta_time, ref_tel, compare_tel = utils.delta_time(ham, lec)

fig, ax = plt.subplots()

ax.plot(ref_tel['Distance'], ref_tel['Speed'],
color=plotting.TEAM_COLORS[ham['Team']])
ax.plot(compare_tel['Distance'], compare_tel['Speed'],
color=plotting.TEAM_COLORS[lec['Team']])

When executed returns this

get_pos_data() inconsistent logic with get_car_data()?

Dunno if I'm trying to do something I shouldn't; very new to this (and to Python). Noticed official timing app seems to be getting the telemetry data once again so I tried to see if telemetry would work again...

import fastf1 as ff1
ff1.Cache.enable_cache('/a/local/directory/i/have')  # pointed to a local dir
race = ff1.get_session(2021, 1, 'R')
lap = race.load_laps(True,) # to get telemetry with this

ham = lap.pick_driver('HAM')
# test code
tlm = get_telemetry() 

I got the following error:

Traceback (most recent call last):

  File "<ipython-input-6-182498178710>", line 1, in <module>
    tlm = ham.get_telemetry()

    pos_data = self.get_pos_data(pad=1, pad_side='both')

  File "\site-packages\fastf1\core.py", line 1573, in get_pos_data
    pos_data = self.session.pos_data[self['DriverNumber']].slice_by_lap(self, **kwargs).reset_index(drop=True)

  File "\lib\site-packages\pandas\core\generic.py", line 1785, in __hash__
    raise TypeError(

TypeError: 'Lap' objects are mutable, thus they cannot be hashed

I wonder if there's an issue in the get_pos_data() since it seems to call ['DriverNumber'] instead of the actual drv_num. Compare the following lines
from get_pos_data
from get_car_data

Does anybody know what the issue is here?

F1 is breaking this on purpose, and they are probably right

Hello,
I hope my words are not taken badly, but I would like to suggest to put a sort of login procedure at the beginning of the connection which will allow only those who have a subscription to the f1 account to access the data. The F1 app is a paying app and by using this script you are allowing anyone, even those who do not have a subscription, to access the data. This was probably discovered and now F1 is removing the files on purpose, since it is removing just the data files this script basically use. So, if I may suggest, I would reconsider the policy of this app because the more you push for letting the data free of paying, the more F1 will make it difficult to get them and since the rest of the public are paying to see the numbers I personally believe they are right.

DRS Integer Values

I was digging through the telemetry data and I was curious about the DRS integer values.
I was not able to find anything in the documentation. Here is an example from another thread it has already been plotted:

Some drives have clean data sets of {0,1}, while other have a range of values from 0 to ~14.
Is there any insight to be had with the range of values or just an artifact of the data that is being pulled?

Thanks!

get_car_data() / get_telemetry errors

Having an issue pulling the car data:

race = ff1.get_session(2021, 9, 'R')
laps = race.load_laps()
ver = laps.pick_driver('VER').pick_fastest()
ver_car = ver.get_car_data()

As result I get the output below

Traceback (most recent call last):
  File "graphing.py", line 29, in <module>
    ver_car = ver.get_car_data()
  File "/Users/.../Library/Python/3.8/lib/python/site-packages/fastf1/core.py", line 1919, in get_car_data
    car_data = self.session.car_data[self['DriverNumber']].slice_by_lap(self, **kwargs).reset_index(drop=True)
KeyError: '33'

Same when trying to get telemetry data instead of only car data:

race = ff1.get_session(2021, 9, 'R')
laps = race.load_laps()
ver = laps.pick_driver('VER').pick_fastest()
ver_car = ver.get_telemetry()

As result I get the output below

Traceback (most recent call last):
  File "graphing.py", line 29, in <module>
    ver_car = ver.get_telemetry()
  File "/Users/.../Library/Python/3.8/lib/python/site-packages/fastf1/core.py", line 1891, in get_telemetry
    pos_data = self.get_pos_data(pad=1, pad_side='both')
  File "/Users/.../Library/Python/3.8/lib/python/site-packages/fastf1/core.py", line 1933, in get_pos_data
    pos_data = self.session.pos_data[self['DriverNumber']].slice_by_lap(self, **kwargs).reset_index(drop=True)
KeyError: '33'

Is this also related to the DriverNumber != drv_num issue?

Information and Features

Is it possible to have a similar feature in Fast-F1 or another program that allows you to have a live telemetry graph (instead of that shit F1 graph in the app)?

I open this issue because I saw that now we need to register the live packages, so (non-programmer hypothesis) the work is halfway.

Thank you

Drivers' DNF

Hello!
I am having issues when I try to use the get_driver(str) method. It's behaviour is very strange, since sometimes work but sometimes doesn't. (specially with the dnf attribute)
This is the error I get:

race_session =fastf1.get_session(2004,6,'R')
print(race_session.get_driver('MSC').dnf)

if info['Driver']['code'] == identifier:
KeyError: 'code'

However, with 2002 and 2003 sessions works correctly.

Is there any other way to know if a driver had a DNF?
Thanks

Hello, I found on the official F1 site that there is a link called http://api.formula1.com/v1/event-tracker . I am not much a developer and learned a little bit python in school so just posted if anyone finds it useful.

End of the session

Hi! Is there any method to know when does a session end?
Especially for qualifying sessions, just wanted to know at what time of the session does the chequered flag appeared.
(it is to know if a driver crossed the line on time and by how much)
Thanks

Session data doesn't seem to load.

I am not able to load session data for any Grand Prix, while I was able to do a couple of days ago successfully.

`import fastf1 as ff1
from fastf1 import plotting
from fastf1 import utils
import matplotlib.pyplot as plt

plotting.setup_mpl()
ff1.Cache.enable_cache('./cache')
session = ff1.get_session(2021, "Zandvoort", 'Q')`

I do not get any output for the request.

Laps on intermediate tyres not accurate

Several drivers had stints on inters at Spa FP1/FP2 and these do appear when running:
pd.DataFrame(session.load_laps(with_telemetry=True).pick_driver(driver))

However, they are missing when filtering accurate laps:
pd.DataFrame(session.load_laps(with_telemetry=True).pick_driver(driver).loc[all_laps['IsAccurate'] == True])

Documentation

Hi, could you add some examples and more precise documentation on the livetiming module and how to extract the data, etc.?

Italian GP FP2 Sainz Data

Hi, I'm trying to see the data of Sainz' accident but there are no data and times for that lap. I checked on the app and the data is there. Do you know how to solve this?

No lap data pre-2018

For some reason I cannot load lap data for any quali or race session before 2018. I just keep getting the message "No data for this session! Are you sure this session wasn't cancelled?" but then in 2018 the lap data magically appears.

Looking for the specific requests that fail and why, I get this when I got the URL for a race pre-2018:

NoSuchKey The specified key does not exist.

Not sure what to do from here.

Not working pip instal!

I'm trying to install a package, but I get this pip install git+https://github.com/theOehrly/Fast-F1.git

[Question] Pick specific lap

Hi, I know I can use pick_fastest() to get lap with best LapTime, but is it posible to pick a specific lap (i.e Lap 10 from race). I want to see the speed of a specific lap of a certain driver. Thank you!

Telemetry for lap 1?

Hi! I wanted to know if it is possible to get the telemetry of a crash on lap 1.(Sainz in sochi 2020 for example) Looks like there is no data recorded for his car, so we cannot access even the start of the first lap.
Any suggestions to access to it?
Thanks

As the title suggests, the program does not work for FP1, FP3 and Q of the Sakhir Grand Prix. The return of the data fetch is None

[Good news] Telemetry data seems to be available after session

It seems that now livetiming.formula1.com has all telemetry data available after session. So probably no longer need to record the live timing data during a session. Below is the data for Imola race:

Season data

Hello, first of all very nice work on fastf1. I was wondering if it is possible to get information about a season? Like the number of races, or a list with the races.

Different question: is it possible to get a session/weekend/race by date instead of year and gp name?

Kind regards, Tijmen
