I'm experiencing this issue as well. Our cloud platform is running Pandas 0.25.0 and the even the Pandas tutorial example from the Influxdb site does not work (https://influxdb-python.readthedocs.io/en/latest/examples.html#tutorials-pandas).
Reverting to Pandas 0.23.4 does work, however that's not a practical solution for us.
I had the same situation.
I reviewed codes & found it's caused by a change on DataFrame.to_dict()
.
You may specify protocol="json"
for write_points
. If so, a tentative solution is to use protocol="line"
, since a problem is in a method for conversion from dataframe to json.
Before pandas v0.24.0 to_dict
for empty dataframe returns an array of empty dicts & its quantity is same as the number of row of the dataframe.
From v0.24.0, it returns an empty array, without any dict.
In _convert_dataframe_to_json()
(a method called from write_points
), to_dict
is used to generate some variables & it is zipped with other variables. Due to the change on pandas, the zip doesn't work well now, i.e. returns an empty iterator.
As the line protocol option on write_points
does not use to_dict
, I could confirm my code worked well with it (my influxdb package is v5.2.2 & pandas is v0.24.2). I would like to tentatively use this instead of json option.
Yes, this needs to be fixed. I'm looking into this now...thanks a lot for your patience!
Thx for reply. We will try the 'line' protocal in write_points as the work around. We will be looking forward to have final fix.
Thanks once again

I advocate for this to be fixed as well. New user to Influx DB -> very frustrating.
Same issue... was struggling to figure out why it wasn't working.
This issue is somehow closely related with the issue #696, in fact even for that issue it is necessary to downgrade to Pandas 0.23.4. Please fix the issue, otherwise it is not possible to use colab with influx data.
Any updates on this issue? I cannot write a dataframe into influx
I tried to push Pandas Data Frame using write_points of DataFrameClient object (Python Package: 5.2.2).
It did not write and did not throw any exception in Influx log too when I did tail -f command.
Then I downgraded Pandas Package to 0.23.4. Then write_points method is able to push the data into InfluxDB. I feel that it is short term fix I figured out. But Influx client package must be fixed.
Can you pls. support on this front.
