_tfq_simulate_ops.so cannot open shared file #757

Open deepquantum88 opened 1 year ago

deepquantum88 commented 1 year ago

Hi,

I am installing TFQ (0.7.2) on python=3.9.7 version and TensorFlow 2.11.0, protobuf=3.17.3. But throws an error. Earlier I worked with TFQ (0.7.2) with python 3.8.16 and TF= 2.7.0. It worked fine.

But now i have to use python=3.9 and it throws an error of file _tfq_simulate_ops.so.

Please help.

I don't think 2.11.0 support is finalized yet (see https://github.com/tensorflow/quantum/pull/756 and https://github.com/tensorflow/quantum/pull/755). When it is finalized it will be through TFQ nightly, 0.7.2 requires TF 2.7.0 (see the requirements file for 0.7.2: https://github.com/tensorflow/quantum/blob/v0.7.2/requirements.txt#L8)

can you please specify the steps to install with bazel. I checked tfq website. and installed bazel 5.3.0. But not sure how to make it compatible tf2.11.0 and tfq with bazel.

To install with bezel, see the install from source instructions: https://www.tensorflow.org/quantum/install

I tried installing but it throws an error of undefined symbol _ZNK10tensorflow80p....

Hmmm there are probably other issues in TFQ that need to be fixed before being stable than, TF 2.11 support will probably be out with the next release.

deepquantum88 commented 1 year ago

any hope when it will be released?

lockwo commented 1 year ago

I do not know the release schedule for 0.8, though there was a 11 month gap between 0.7 and 0.6, and a 8 month gap between 0.6 and 0.5 for context.

Please, please rebuild TF 2.11.0 with the right build options: ABI is set to 1, std c++ is 17.

Here is the newly updated installation guideline:
