Cannot reshape a tensor with 2705220 elements to shape [6441,127,1]

Hello，I am using this ipynb file on Colab
https://colab.research.google.com/github/sokrypton/ColabFold/blob/main/AlphaFold2.ipynb

When I did the Gather input features, predict structure step. I found an error.

Running model_1
InvalidArgumentError Traceback (most recent call last)

During handling of the above exception, another exception occurred:

Hmmm... it worked for me. Were there any other options you enabled/disabled (compared to default)? Can you try "factory reset" and run all again?

It worked after I restart the environment ! The second running failed.

[sokrypton]

For the "second running" are you changing the sequence?

[sokrypton]

Fixed it! You should be able to run again with second sequence without needing to factory reset.

Thanks for the report!
