Errors when rendering pdf

Hello I'm having an issue in saving pdf from plotly images. I can save them as html, svg, but not in pdf. When I run

import os
import plotly.express as px
fig = px.scatter(px.data.iris(), x="sepal_length", y="sepal_width", color="species")
tmp = os.path.join(os.getcwd(), 'tmp')
fig.write_image(os.path.join(tmp, '00.pdf'), engine="kaleido")

I get the error:

ValueError: Failed to start Kaleido subprocess. Error stream:

I tried a workaround with

import os
import plotly.express as px
import plotly.io as pio

pio.kaleido.scope.chromium_args = tuple([
    arg for arg in pio.kaleido.scope.chromium_args if arg != "--disable-dev-shm-usage"
])
fig = px.scatter(px.data.iris(), x="sepal_length", y="sepal_width", color="species")
# tmp folder
tmp = os.path.join(os.getcwd(), 'tmp')
fig.write_image(os.path.join(tmp, '00.pdf'), engine="kaleido")

and still gives an error:
