Error about "UnsupportedOperation: fileno"

[FJGEODEV]

Hi, I was trying to run Devito on a BP's TTI dataset based on this repo:

https://github.com/ofmla/RTM----segyio-devito-

But after reading necessary velocity parameters, this error came out. Have no clue to solve it, could you help to take a look?

I am running it under Amazon SageMaker, Tensorflow 1.15, Python 3.7

Thanks.

@speglich Does this ring a bell?

Hi, wondering if you have any thoughts on this error. Thanks.

[navjotk]

Can I just check how you installed pyrevolve?

[speglich]

Hey @FJGEODEV, what is your installed PyRevolve version?

[FJGEODEV]

Hi, I believe this could be caused by this issue #57. I can submit job using .py file, will upgrade pyrevolve to test.
