[Bug] fix for the bug I had about fsrs4anki

[Vilhelm-Ian]

language.zip
I am not using an official anki version I compiled it from source when you released the first version of fsrs4anki. I am happy with the algorithm I have less reviews now

[Vilhelm-Ian]

I tried with a different browser it worked. Look how few reviews I will have with fsrs4anki

Good news! And the figure shows that FSRS reduces the reviews nearly 30% than Anki.

Could you help me test the fix version?

Please use the older version of Anki to export the .colpkg file.

Please use the older version of Anki to export the .colpkg file.

I get the error with apkg also. And I marked that option

Could you share the apkg file with me? I assume it was caused by some new features in the latest version of Anki. By the way, which version did you use?

[L-M-Sherlock]

So weird. I use google colab to execute the optimizer with your language deck file. It works well. I don't know what caused the error in your case. I assume the colab is the same for us?

[Vilhelm-Ian]

it should. I now this shouldn't affect the result maybe because I am using linux

Had same error. Tried with a different browser and worked.

Which browser did you use?

FIrefox. Maybe some addon was the source of the error.
