Multiple errors when trying to install tensorflow gpu beta 2.0 in virtual env on a windows machine using pip

Missing instruction `_mm_crc32_u64` when installing clickhouse-cityhash on OSX 10.14.5

Which string hashing algorithm produces 32-bit or 64-bit signed integers?

Multiple errors when trying to install tensorflow gpu beta 2.0 in virtual env on a windows machine using pip

Asked 2019-Oct-15 at 17:12

I am trying to install tensorflow 2.0 beta on my windows machine using pip. I am using the requirements.txt from https://github.com/ageron/handson-ml2/blob/master/requirements.txt

The only change I have made is to use the beta tensorflow version instead of the tf-nightly-preview version.

#tf-nightly-2.0-preview
#tf-nightly-gpu-2.0-preview
tensorflow-gpu==2.0.0-beta1

I am getting three errors -

In the newer commits for tfds - the cityhash library has been swapped with siphash.
For tensorflow the tb_nightly dependency is expected to be updated mid-July so if installing after that - the issue may not even arise.
Since cloudpickle versions for two packages are different need to upgrade one of them or downgrade the other.

Many thanks to @PeterCordes for his very valuable observations in the question comments above!

The failing build command during pip install clickhouse-cityhash included the -arch i386 flag. The default behaviour of x86 clang is to build 64-bit code despite the presence of this flag.

However, this does not appear to be Apple clang's default behaviour. If 32-bit code is generated then _mm_crc32_u32 would the largest CRC available, implying that _mm_crc32_u64 is not defined.

Therefore, one solution is not to use Apple clang.

Most developers using OSX will be familiar with the brew package manager and have it installed. You may find that you already have a version of gcc installed via brew as a dependency of another package.

QUESTION

Which string hashing algorithm produces 32-bit or 64-bit signed integers?

Asked 2019-Mar-30 at 19:59

I want to hash strings of variable length (6-60 characters long) to 32-bit signed integers in order to save disk space in PostgreSQL.

I don't want to encrypt any data, and the hashing function needs to be reproducible and callable from Python. The problem is that I can only find Algorithms that produce unsigned integers (like CityHash), which therefore produce values of up to 2^32 instead of 2^31.

This is what I have thus far:

create or replace function int_hash(s text)
returns int as $$

    select ('x' || left(md5(s), 8))::bit(32)::int
